I agree that "it is best" to not actually put a lot of graphics or other binaries into a physical database however there are times when it is very helpful. To see a simple step by step demonstration (plus a demo of how to have any graphic retain it's aspect ratio within a defined area ... great for printing thumbnails and letting users add their own logos to your multiuser database apps) click over to:

It's the same deal if you want to add graphics, wavs, avis or any other binary files ... I use this same method and some repolication code to keep all of my ocx and program patches in a searchable jet database spread across multiple zip disks.
