Do you mean still pictures?
In which case do you mean just panning across them like there lying in a room. Or do you mean showing them full-screen panning from on to the next?

Make Love Not War!

Full screen, panning from one to the next, fading and zooming in going across the picture.

In Premiere you can just import pictures and use them like videos, you can do any effect you could do with a video. I'm not so familiar with other programmes but I would assume they were similar.

I'm assuming you're talking flat art.

The most extravagant way is to get an animation stand, or something like one. This is a stand which holds the camera in one position, while the artwork is moved below it. The artwork can be moved left to right, up and down, and further and closer to the camera. It requires much patience and a pretty solid concept of exactly what you want the final product to look like. Barring that, it requires a lot of footage of variations of zooms, pans, dollies, etc.

An easier way to do this is by importing the art (again, it's gotta be flat art, so no frames (unless you've got a picture of your art in a frame)) into an editting program and using panning and scanning to manipulate it. I think Final Cut has something that does this, and I know iMovie has something called Ken Burns Effect which does exactly this. The benefit of this is you can experiment with timings to get things that match exactly your cuts, music, mood, whatever. Ken Burns can be very choppy, especially if the moves are too large.

If you need 3d art (photos in frames on desks) you're back to shooting tons of variations, unless you use something like Ken Burns' Effect to work out your sequence in your cut. Keep in mind your camera should be on a tripod (small movements look huge here) and light the scene just like it is in your master.
