graphics files

[Ronald C. Cheshier]

I am in the process of putting together some WEB pages for my lab and and 
trying to locate GIF files of a scientific nature, pictures of microscopes, 
chromatographic charts, spectrophotometers, that sort of thing.  If anyone has 
these types of graphics or icons I would appreciate a few postings or if 
someone knows of a WEB site library, I would appreciate the information.
