Welcome Ladysnape
As long as you've got permission (usually from the copyright holder or from someone who has the power to give permission on behalf of the copyright holder), there's no problem at all with pics...but ya gotta be really careful. It's not just copyright which is a possible minefield but also if you're hot-linking to an image from someone else's site, this is a use of their bandwith, so you'd need to make absolutely certain that the hot-linking is authorised too.
As long as you're absolutely certain of all that, though, pics are a totally fine addition to the board and a nice addition of color.
It all sounds horribly official-sounding I know, but basically it's legal stuff and sites can and do get closed down or worse if they don't stick to these things.
The easiest way of course would be to create your own non-trademark-infringing pics. if anyone has their own piccies they've created and would like to be able to put on the board, just ask it can be sorted
