I'm making a booklet for my youth movement organisation in which different texts, games and ideas will be listed. Since several people will be adding content it seems like a good idea to make a template in Latex and include lots of .tex files.
I'm making the template right now and I have a question about the design.
I do realise there's a small chance that what I'm looking for is possible, (please don't waste too many replies in telling me so) but Latex has amazed me before, so here goes

In order to perk up the booklet I would like to automatically add small images to the background (small photos or vector images). Since the booklet will contain lots of snippets I assume there will be quite some white space. Is it possible for Latex to detect great area's of white space and place a image in the background of this area? In the ideal case this images would be selected randomly from a folder and placed randomly with a maximum per page. Is this anywhere near possible?
Please tell me if you know something to accomplish a small aspect of everything I described above.
Thanks in advance!
