I don't know what units the resolution is measured in: dots per inch or dots per meter or whatever. And as to what formats indicate resolution, all I did was open a bunch of files in ThumbsPlus and see which ones had a resolution listed. It's possible that BMP files have an optional resolution field, and the file I checked didn't use it.
