For the professional digital photographer, image integrity is important.. Because the quality and resolution is so important in good photos, the structural images of JPSs, TIFFs and so forth are very important. ImageVerifier goes into an image format, decompresses it and tells the professional digital photographer all he needs to know concerning the integrity of the image file. It verifies active and archived images in a structural manner and by storing 512-bit hash. It carefully assesses the image and encsures that it is backed up without losing integrity. Because this product is free, just suggesting this program is available, would make a nice gesture during the Christmas gift-giving season.
