It depends on how the image was faked. If it was a original jpeg and one did a half-bad job, a pixel by pixel survey might spot it. But if the original was a raw image for instance, and the manipulation was done with some care, and the end result is a jpeg with higher compression then it is a lot harder to spot. There might be some mathematical statistics calculation to see odd differences in the compression, but that i cant say for certain. -- /Rikard ----------------------------------------------------------------------------- email : [EMAIL PROTECTED] web : http://www.rikjoh.com mob: : +46 (0)763 19 76 25 ------------------------ Public PGP fingerprint ---------------------------- < 15 28 DF 78 67 98 B2 16 1F D3 FD C5 59 D4 B6 78 46 1C EE 56 >
