trying to create a texture map for a 3d model i made in another app, basicly a hardwood floor =P

i have a 2nd picture with wood samples (nicely made for using to create textures), and instead of cut/paste by hand, and alligning them on the floor file, is it possible to make a script that draws up random numbers (within a range) and cuts out (well copy out) a part of picture A, depending the numbers it created, and pastes into picture B at a specifit spot (preferably by a saved/edited variable to change?) as it progresses?

i've been trying to find an answer to this but so far nobodies come up with a workable solution.

i'll keep trying, just wanted you to know...
