Thanks, yes I tried Photogene...it seems you can change the number of pixels but when I tried to print the size of the image was full A4, just v fuzzy! I found a bit of a workaround - I cropped the image in Photogene, saved it to Camera roll, then went into Pages and opened the image there from the camera roll.. Pages allows you to play with the size in actual cms when you click on the border of the pic, so I made it the size I wanted and printed it out from there. Seems a bit of a long road for a shortcut, though!
