As you know bitmaps are huge and take up a lot of memory if you want to use a graphical interface or graphic buttons. My solution is to use rle compression to reduce bitmap size without the JPEG artifacting. Using shareware like Paint Shop Pro, I set up a batch conversion to rle (a cross-compatible subset of the bitmap format). I then rename the the rle's to bmp's in rbase and import into the database for use as varbit varables in forms and reports.
RLE works best of images with a lot of solid color. Gradients and photos are best left to jpeg. One issue is that if your users are running in 256 color mode, you have to set up a standard 256 color pallette which could lead to some color loss in the graphics.
