I didn't even know qimage could print several sizes at once (which is very good), but i'm not sure how many people used this extra.
I print my 4x6 photos first, then change my printer paper to 5x7, and then print my copies at that size. Most printers (non-professional) do not have trays for each size of paper so I can't print multiple sizes at a time. My printer is the Epson L805 and enough for my business.
I'm talking about printing in one size only! The "+" button adds only one photo and the button "-" removes one photo. Thumbnails show only the number of copies that will actually be printed.The checkmark at the top of the thumbnails indicates whether or not you selected a photo to print, if not selected, the copy selection becomes inactive.
I don't want to quarrel with you, just make a suggestion that would be better for the software. Before I used Epson's software, and the only good thing about it was to see how many copies I had selected for a each photo. I just choose the copies of the thumbnails and print it (in one size).
But you are programmers and you know what's good and what's not. I just have to get used to it the hard way
So I also maked the poll to see if there were other users like me who had difficulty choosing copies.
Once you think this is too complicated and does not make sense, then there is no sense of this topic. :-\
