infinity magnet cubes

[Gareth]

Have you looked at getting any of the sticky back magnetic sheets. OG games stock them, not sure on price though. But you can cut it easily, stick it to your foam board, then attatch the paper picture to your structure. As long as polarity isn't an issue on the paper it should work.

Also may be worth looking at the Terraclips that Malifaux are soon to release. You'll understand better when I haver set come through, but they are a pack of various clips that you use to hold printed card together, into various pieces of terrain.
