In depth
A closer look at pngcheck
pngcheck is a simple, easy to use application designed to verify the integrity of PNG, JNG and MNG files by checking the internal 32-bit CRCs [checksums] and decompressing the image data. It can optionally dump almost all of the chunk-level information in the image in human-readable form. For example, it can be used to print the basic statistics about an image (dimensions, bit depth, etc.); to list the color and transparency info in its palette (assuming it has one); or to extract the embedded text annotations.
