Small program to get detailed information on images

adobe-photoshopimage-viewerimagessoftware-rec

I'm looking for a small program that will show be a LOT of detailed information about media files, specifically images. For example, I'd like to know if a .BMP file is Windows or OS/2, Compressed, etc.

Windows tells me the basics and Photoshop can read files just fine, but I want to know exactly what format an image is.
