Image formats (generally, and I acknowledge there may be problems with those that do not) contain sufficient information, jpeg and png both tell you the size of the image (in inches, cm's or whatever aswell as having their own pixel size. I believe there's a Image::Size module for perl which will do this for you (I was actually using in the situation that finally made me realise it is actually debilitating aswell as being wrong, but have since abandoned it as I didn't like the server load.) There's no difference between the information in a jpeg, and the information within the the SVG file I created to demonstrate it. Jim.
