Images are always displayed in their original orientation because images are presumed to be "upright" as shot (or edited)... which means the original image of that tree is laying down on it's side as shown in the multi-panel print dialog.  You can still do the job with the image rotated but if you want it to appear rotated differently in the multi-panel print editor, double click the image to open it in the editor and then apply 90 (or -90) rotation to fix the orientation of the image.

I don't know what you're doing so there's no way for me to say where you are going wrong.  The only way you wouldn't be able to get three panels of 18x24 is if that doesn't match the final print size.  I have no idea what you are doing so 3 panels of 18x24 could either be a print size of 54x24 or 18x72.  If your print size isn't either of those sizes, three panels of 18x24 is not possible because it wouldn't be divisible by 3.

Of course not.  You are printing panels so the panels you are printing are 18x24 and the only requirement is that your printable area be at least 18x24.  So if you look on the main window above the live view where it says "Page:", it has to be at least 18 wide and 24 inches tall or the reverse: 24 inches wide by 18 inches tall.  Panels are the least common denominator so if your printer can't print at least 18x24 on a "page" (sheet or roll), you have to reduce the panel size to something it can print.

So assuming you have a printer that is capable of printing 18x24 prints on one sheet of paper (or a roll), you can print three 18x24 panels that add up to a total of 54x24:

• Under print size, make sure the crop button is turned on.
• Just enter 54x24 up top as the "Print Size".
• Click on the cols/rows tab and enter 3 columns, 1 row.
• Click the "Generate" button.

You said you are using a 24 inch roll so you realize you probably can't get exactly 24 inches across without doing borderless (no margins) which isn't something you want to do with multi-panel prints.  So if you can't get the full 24 inches across, you may need to just make the length of the paper on the roll something greater than 24 inches so you have 24 inches of length to print with: then the panels will fit 18 inches across the roll rather than trying to squeeze 24 inches onto exactly 24 inch wide paper... but you can still do it.  Just keep in mind the prerequisite: that "Page:" size listed on the main window has to say 18.0 inches or greater in one dimension and 24.0 inches or greater in the other.  Otherwise it is impossible to print 18x24 panels.

If it doesn't work, you didn't follow the steps or your page size is less than 18x24.  I'm not going to continue trying to guess what you are doing with no information about your specific setup so if you want further assistance you are going to have to create a video or screencast showing your steps.

Thanks.  That helps: now I can see what you are doing.

Look at the top of the multi-panel UI: your print size is set to 19.76 x 26.35.  So when you enter 3x1, it is splitting up 19.76 x 26.35 into 3x1 panels.  It did that correctly because you can see all three panels side by side on the live view when you are done.

So you're skipping the step in my instructions where you specify 24x54 as the print size.  It needs that final print size so when you enter 3x1 it knows how big to make the panels.

I think what I am trying to do is using an image which is 19.76x24.05" and trying to split that up into 3 18x24" panels. To me this would mean the image would have to be much larger in physical size in order to get 3 18x24 panels out of it. I do get 3 panels but they are only between 4 and 6" wide by 24" high. I don't think Qimage can make these 3 18x24" panels needed out of a 19.76x24.05" image?
