Can you clarify the origins and state of the bitmap files? For example, were the bitmaps generated by the notebook front end by converting a graphics cell to a bitmap from a menu command? Or were the files created by a third-party application, and you want to import the graphic into the Mathematica kernel? What is the format of the bitmap (e.g. TIFF, JPEG, GIF, etc.)? What platform are you working on? -- P.J.
