this might be strange question
a jpg of mine got edited accidently, with the edition of some black smudges - just 1 colour in a few places. this was then saved. i thought the image was doomed, but when i view the thumbnail, i can still see the original, unspoilt image. this happens even when i copy the image to another computer, so its not just what is saved in the thumbnail file.
any idea whats going on? can i restore my jpg to its previous version? is the original image hiding under the black somehow?
cheers
