Trouble finding the proper workflow for what you need to do:

Trouble installing Qimage:

Ensure that the downloaded demo is intact and that you downloaded the installation file to a folder with no other files present in that folder. Once the installation file has been downloaded, go to the folder that contains (only) the installation EXE file and run the EXE file using "Start", "Run". The most common problems related to installation are trying to run the installation file from a folder with other files (possibly leftover remnants of other installs) and trying to manually unzip the files in the EXE when you should run the EXE directly using "Start", "Run" instead. Also note that some software may interfere with InstallShield installations so try rebooting and running the installation before using any other software.

Trouble starting Qimage (errors/crashes on startup):

Trouble when opening certain folders:

If Qimage reports errors or crashes every time you navigate to a certain folder using the folder browser above the thumbnails, it is most likely encountering a damaged/corrupted image. Qimage has sophisticated error detection to prevent crashes even when images are corrupted, however, since there are an infinite number of ways that an image can be corrupted, it is possible that Qimage may encounter a file that causes trouble and makes it past the file format validation. Remember that Qimage builds thumbnails automatically for every image in a folder as soon as you visit that folder, so any image in that folder could be causing the problem. Try restarting Qimage and clicking "View", "Interface Options", "Thumbs or Files", "Names Only" prior to entering the folder. You will be able to enter the folder without a problem since Qimage will not try to access all images in the folder. You may then examine individual images one at a time using the space bar to display images under the mouse pointer, or simply add all images to the queue and run a slide show. Once the damaged image is located, you can delete the image or move it to a different location. Locating damaged images is much easier when you file your images in different folders. If you have one massive folder called "My Pictures" where you dump all images, locating a damaged image can be difficult.

Some causes of corrupted images:

Trouble when viewing/editing images on screen:

If you get an error message such as "bitmap not valid", "parameter is incorrect", or "error in imagelib.dll", you may be opening an image that is too large for your available memory. If you are opening large images, make sure you have enough RAM installed and also check your Windows virtual memory settings and try increasing virtual memory. If you are running Windows 98 SE and you are encountering these errors often, even when opening images that do not appear too large for the available memory, upgrading the operating system often resolves the issue.

Note that corrupted images can also cause errors when viewing/editing so be sure to check the information on corrupted images above.

Thumbnails appear smudged or do not update properly:

Qimage locks up or is unresponsive when applying a filter:

If there is simply no response and you still have the hour glass showing on screen, Qimage is just not finished running your filter. There are many filters available that are time-intensive and these can be combined to create filters that take several minutes (if not longer) to run. For example, running a plugin along with the D1 ISO filter will take about 30 seconds on a 1.0 GHZ Pentium. Adding the shadow noise filter or other filters can double or triple this figure. Just be aware that the more complex you make your filter (the more parameters you change), the longer the filter will take to apply. In addition to complexity, you may have told Qimage to apply the filter to 100 images in the queue, at which point it could be hours before control returns to Qimage.

When applying filters using the batch filter, the "parameter is incorrect" error appears:

An error appears as you move the mouse pointer over the thumbnail or file area:

One or more of the images in the current folder could be corrupted or unreadable for some reason. When you move the mouse over the thumbs/filenames, the EXIF Hotbar attempts to display EXIF information on the bottom status bar. If an error occurs, try turning off the hotbar using "View", "Interface Options", "EXIF Hotbar" and uncheck the option. When starting Qimage, make sure not to move the mouse pointer over the thumbnails until you turn off the EXIF Hotbar. If you are unable to start the program, try starting Qimage in safe mode by holding the shift key as you start the program. You can then turn off the EXIF hotbar and reset the interface to thumbs if you like.

Trouble when printing images:

Trouble that includes an error message could indicate problems with corrupted images or memory: see above. Trouble like partial prints, not all prints printing, blank pages, or anything that deals with missing information in prints (with no error message) is usually related to a data bottleneck in the operating system. Due to its print optimization, Qimage sends more data to your printer than most software, so you may or may not see issues with other software while at the same time experiencing trouble with Qimage. The suggestions below will help eliminate printing problems caused by improper Windows configuration:

Printed color or contrast is incorrect when printing large prints:

If your prints appear to have good color for smaller sizes but get too light/dark when you print the same prints at larger sizes, the print driver may be having trouble with its automatic contrast/color feature. Some printers have "enhancement" or "digital photography" features that attempt to auto-adjust contrast and color, however, these automatic enhancement features may fail when printing large prints. Click "File", "Printer Setup" and "Properties" for your printer and browse through all the tabs/features, turning off (unchecking) any features that are described as "auto" or "enhance". With some poorly designed print drivers, auto-adjustment features may not work properly when printing large prints because the driver cannot handle the automatic adjustment when presented with the large amount of data needed for large prints.

Color of prints does not match other software:

Unless you are using PIM, EXIF Print, or some other proprietary printing technology, Qimage can match printed color to any other application. The key in matching printed color is to ensure that the print driver settings are the same in both programs and that ICC profiles are being utilized in the same way. As long as you use the same print driver settings, you load the image using the same color space for the image, and your printer ICC profile is the same (labeled "Prtr ICC" or "Print Space), the color of your prints should be identical in Qimage compared to other "high end" imaging software. For example, both Qimage and PhotoShop render identical printed color as long as the print driver settings and color management settings (ICC profiles) are the same. If there is a difference, your settings are different either in the print driver or in the color management settings, so you will need to recheck all settings carefully.

Print resolution listed above preview page does not match DPI selected in driver:

This is actually not an indication of a problem. The resolution (DPI) selected in the print driver properties indicates the resolution of the printer itself. Qimage reports the native resolution of the print driver, i.e. the PPI that the driver suggests using when passing information to the driver. You may, for example, select 2880 DPI resolution but Qimage reports 720 x 720 over the small preview page on the main window. This is normal since Qimage will send the data to the driver at 720 x 720 and the driver is then responsible for placing the actual dot patterns at 2880 DPI. Simply put, your actual prints will be printed with the DPI selected in the driver.

Trouble selecting a page size other than 8.5 x 11:

The page size in Qimage is selected via the print driver. Click "File", "Printer Setup" and change the size of the page from the properties of your printer.

"Stream write error" or "unable to create {q}work.{q}":

Error messages such as "stream write error" or "unable to create {q}work.{q}" may indicate a problem writing to your hard drive.

"Spool one page at a time" option does not work under Windows NT/2000/XP:

If you are trying to limit the size of print jobs, using the option to "Spool one page at a time" located under "Edit", "Preferences", "Printing Options" can prevent crashes caused by the operating system or print driver not being able to handle large jobs.

Unfortunately, the "Spool one page at a time" option will not work under Windows NT/2000/XP unless you tell the operating system to stop "squelching" print spooler messages. We do this by setting the registry entry named "EnableBroadcastSpoolerStatus" to a value of 1 instead of 0. This can be done by using "RegEdit" to change the value of the registry entry. Please note that if you are unfamiliar with using RegEdit, it can be dangerous to play with values stored there unless you know exactly what they do. Perform the following steps at your own risk!

To configure Windows NT/2000/XP so that "Spool one page
at a time" will work, follow these steps:

  1. Click "Start", "Run" and type "Regedit" and click "OK"
  2. Double click to open HKEY_LOCAL MACHINE
  3. Double click System
  4. Double click CurrentControlSet
  5. Double click Control
  6. Double click Print
  7. On the right half of the window, you should see an entry
    for EnableBroadcastSpoolerStatus.
    If the entry does not exist, right click on "Print" on
    the left side of the window and select "New",
    "DWORD Value". Then type the name:
    EnableBroadcastSpoolerStatus. Once this entry has
    been located or added, Double click on
    EnableBroadcastSpoolerStatus in the right window to
    change its value data.
  8. Under "Value data", replace the 0 with a 1
  9. Click "OK" and close RegEdit

Once the above steps have been performed, Qimage's "Spool one page at a time" should work properly. If you still have trouble spooling with a time delay may be the only option that your system will allow.

Print output is blocky or "pixelated":

You may have print interpolation turned off. Check "Edit", "Preferences", "Printing Options" and make sure that you have the "Hybrid" interpolation method selected and a print interpolation setting of "Max" for maximum quality prints. Also ensure that your print driver settings under "File", "Printer Setup" are set for the proper media type and the highest quality.

Print output is blurry or soft:

Inappropriate print interpolation settings can cause this. Check "Edit", "Preferences", "Printing Options" and make sure that you have the "Hybrid" interpolation method selected and a print interpolation setting of "Max" for maximum quality prints. Also check the sharpening settings on that same window.

Print output has horizontal lines:

This is most likely due to a bad or empty print cartridge. Run your printer through it's nozzle check to determine if the cartridge needs to be replaced.

The size of the print is not what you selected:

Unable to print borderless prints:

Below are the proper steps for creating borderless prints:

If you do not get a borderless print after performing the above steps, the limitation is with your printer/driver. Make sure that the borderless option is available for the type of paper you are using as some paper types do not support borderless printing. Also, if your print driver offers an "amount of extension" under the borderless option, try increasing the amount of extension as there simply may not be enough overspray to cover the entire page.

Prints are not centered on the page even when "Center" positioning is selected:

Qimage works within the printable area defined by your printer. The printable area is the area on the paper that the printer is able to address. Due to limitations in paper loading accuracy, type of paper advance, print head design, and other factors, your printer is most likely not capable of printing on the entire page (unless borderless printing is enabled). Instead, most printers print within a defined (smaller) rectangle on the page. This printable rectangle is usually not centered on the paper. Qimage normally centers images within the printable area on the page, thus ensuring that the entire printable area is used. If you would like to center images on the paper itself, compensating for the fact that your printer doesn't print in the center of the page, there are two options:
