Is there a GOOD, inexpensive, or free program out there that I can use to sign my images, that WILL NOT DEGRADE the image??? I ain`t cheap, just short on funds right now. I have a 3.0 ghz sys, windows xp home sp2, 1 gig of memory, 80gig internal, and 80gig ex. hard dirives, ati radeon x300se video card with 128mb of memoy.
