Thumbnail "image read error" - Small seemingly normal JPG

[rossus]

Hey,

I am trying to print a JPG having adjusted it in photoshop. Originally it was sent to me as 46.764x22.389 inches at 72 PPI. When I then increase the PPI to 300 and change the file size to 46x22 and save, QImage will not create a thumbnail and gives the 'Image read Error' in red. It works fine with the original file, and all I am doing is saving as a JPG after changing in photoshop.

I have rebuilt and refreshed thumbs, and also closed and opened Qimage, and nothing works.

Just to add to it (incase it helps), I am running QImage on XP within Virtual Box on a Mac, and QImage is version 2010.209 professional.

Can anyone suggest anything I am doing wrong or missing?

Many thanks in advance

Hi Rossus,
Your problem is probably to do with how the image has been saved in PS.
However, lets go back one step here -

Originally it was sent to me as 46.764x22.389 inches at 72 PPI. When I then increase the PPI to 300 and change the file size to 46x22 and save,

Why do that is PS? You are missing the point of what Qimage does best.
Just use the original image, set the print size to 46x22 in Qimage and print (assuming that's what you want to do). Qimage looks after all the resolution stuff automatically and uses interpolation algorithms that are far superior to anything PS uses.
Your original image is 3365 x 1612 pixels, leave it at that and let Qimage do everything for you - it automatically interpolates on the fly to the native resolution of the printer so it's bad news for quality if you interpolate to some arbitrary resolution in another program first.

Terry gave you perfect advice.
I am the curious one!
Any way you could email that JPG that gives the Image Read Error?
I would love to check it for all of us.

Hi guys,

Thanks for getting back to me. I will send the file to you Fred...thanks for that.

I agree with you about the sizing thing and I usually do, but I needed to add a two inch black border round the file for when the canvas is wrapped on the frame. Unless I have missed something, Qimage doesn't do this.

Again, thanks for your responses. Its a pleasure to know that people out there take time to support others. I look forward to your thoughts on the issue I am facing.

Yes it does, and Terry can fill in the details for you when you need details.

I received your email with the (2) JPGs in the mail that just downloaded when I turned on the computer. I'll have a look in a few minutes.
Thanks for sending it.

See screen shot attached for settings of canvas wrap (mirror) and extra black border. Easy peasy  
Whooops, I mirrored the screen shot too when I re-sized it - Sorted now

Ross,
I am a bit confused when you say you are sending two that failed.
You have one large file, which opened fine and is a wonderful B&W shot. No Image Read Error.!!!
I have no idea what the second JPG is supposed to be. It is only 53K, and will not open in any program.
I tried Paint Shop Pro, CS5, Irfanview, Windows picture viewer, and Qimage.
They all say the same thing: Corrupted file or Unsupported or corrupted.
Qimage pops a message that says there is a corrupted image in the queue, and will be ignored.
From that point on there is a yellow warning triangle, top left of the thumbnails to remind you that there is an image not in the thumbs, and waiting to be removed.

I didn't get any Image Read Error.

Whatever that 53k image file might be, it isn't anything readable.
Maybe you have something from an improper save made in CS5? A different one that is giving the Image Read Error?
Sometimes, folks make a TIFF saved with Mac file settings and get an Image Read Error.

Interested to know,

PS, when I insert your image into Qimage using the Custom; Use Original Size, I get a print that is 46.76 x 22.39. See snap. All that looks perfect!

Hi Fred,

Sorry for late reply...been on hols! 

I took the image that you sent back of the couple embracing at their wedding and tried again in a different file location and got the same error with Qimage. Not sure what is going on. Any ideas?

Thanks Terry for the help with borders too! I will check that out and have a go when I can get this image working!

All the best

Ross,
Maybe Mike will see the thread and come up with something.
In the meantime, I am sending the B&W image to Terry. He is very sharp, and might either get the error or spot some anomaly.
At the moment, the only thing I see (grasping at straws) it seems to have been saved as a Progressive JPG. From what I read, that should not present any problem to up to date JPG decoders.
It opens fine on my two machines running Qimage Ultimate and Qimage Studio.
I even saved and resaved a few JPGS in both methods, and other than file size, I see no difference nor any problem.

I have that now and don't see any problems with it whatsoever.
I see from the exif data that the image was edited on PhotoShop on a Mac.
Maybe the emulator  software to run Qimage on a Mac is doing something to the image, I don't really know.

Hi guys,

Just wanted to say thanks for all your help. I haven't worked out what is causing the issue. However, I have learned enough about the wrapping etc, to get the job done without a need for photoshop, and for that, many thanks indeed.

Sorry it took a while to respond. I work 4 days a week and print just the one!

All the best
