I am not sure about the JPEG, but you can do this to get the BMP:
1. LoadLibrary to load the dll.
2. FindResource to get the resource handle
3. LoadResource to load the resource itself, to get the handle to the bitmap
4. CreateDC and SelectObject with the returned handle to select the bitmap into the new device context.
5. BitBlt to output it

Tell me if you need any help

The best way is to use .RES format in Resource Workshop, and add .RES file to your VB project.
There is VB example in your vb5\samples\PGuide\ATM directory.
It shows how to load picture, cursor, sound or string from your Resource file.

For dlls, it is not that simple. LoadResource is complicated (you must also use LockResource and UnLockResource...). There are easier API functions for each type of resource (e.g. LoadBitmap, LoadIcon, LoadCursor...)
