I think I figured it out. I tried cutting the background into 4 sections and making 4 surfaces and it also didn't work. I compared the new images to the old background I had and saw the new ones were saved as progressive scan JPGs. I resaved them as non-progressive JPGs and it worked fine.

There should not be any size limit on JPG file, but probably algorithm that therion uses to parse JPG file for its size failed. I will try to determine, where the problem is.

In any case, multiple surfaces are possible, but only for PDF output.

Is there a maximum supported size for JPG? My new background is 15,132x11,340. Or is it possible to input multiple surfaces for a background, so I could break that one large image into smaller tiles?

Thanks!
