I believe that image files on the Mac platform contain metadata that does in fact include this information. Sherlock on Mac OS 9 is not capable of finding this information. However, I did find the following information for Adobe Photoshop 7 for Mac OS X on how you can achieve this. I don't know if Adobe Photoshop 7 for Windows can do this.
From: http://www.apple.com/macosx/applications/photoshop/ You have thousands of digital pictures and graphics stored on your hard disk. Wouldn¹t it be cool to be able to verify what¹s in an image file before you click on it? Adobe thought so too, which is why the new File Browser in Photoshop 7.0 lets you do just that. The File Browser lets you view your thumbnails and image metadata ‹ like color profile, date modified, and the Exchangeable Image File (EXIF) information generated by digital cameras ‹ to make sure the images are what you¹re looking for before you open them. As an added convenience, Photoshop lets you add ranking to your file criteria. You can have your own ranking system for identifying images with, for example, rankings such as ³Proof² and ³Final.² You can also sort images by file name, file width and height, file size, file type, resolution, color profile, date created, date modified and copyright. The File Browser also gives you the added advantage of being able to search for images visually rather than just by file name. Eric C. Pollitt, Founder 401 E.

It is a species of intemperance within itself, for it goes beyond the bounds of reason in that it attempts to control a man's appetite by legislation, and makes a crime out of things that are not crimes. A Prohibition law strikes a blow at the very principles upon which our government was founded."
