You can add solid color borders to just one side using -splice

You can append multiple images together verticall or horizontally using +/-append

You can tile images onto a larger canvas using convert tile: or a number of other methods

Do you see a pattern? IM Examples is your first stop!

Bacically, if you want a exact answer, you need to be clear with your question, prehaps with an example image linked from somewhere on the WWW.
