Its to do with image size .I noticed i could print some pics but not others. All those that gave the error message had a resolution of 1 pixel per inch. So click Image tab - Image size ,and change resolution pixels per inch to 72 or other and document size to a reasonable size for printing on normal A4 paper, say 600 by 1000 pixels. My picture that would not print had a document size of 4784520.43mm by 6379360.5mm , thats 4784 METRES by 6379 METRES or roughly 3 MILES by 4 MILES!!! So as you can see its no wonder CS3 dosent want to print it. I still think its CS3 at fault somewhere as the pic is opened ,so just resize image and you should be good to go.
