   What Anders said; BMP is uncompressed and so does not degrade. The only   
   reason to store as JPEG would be to save disk space.   
      
   FWIW, most folk around here only store the path to the graphic file, and   
   use code to display the graphic in an undefined graphics object. This has   
   several advantages:   
   1. Graphics objects stored in tables are notoriously corruption-prone.   
   2. This saves all sorts of space.   
   3. You get to manage your graphics with graphics programs instead of a   
   database program with a few graphics commands.
