In general, all file pointers should be relative to a project root.
That way you can move or rename the job, but the pointers still
work. $HIP should work for that. You could also set the
HOUDINI_TEXTURE_PATH environment variable such that it contains the
directory with all the images. I'm not a big fan of that -- I much
prefer a filepath that's pretty complete, in case I need to debug
something later on, e.g. that Houdini can find the picture but that
Mantra can't, or that a particular server can't.

This won't prevent duplicates -- that's a challenge for another day.
Also, the expression above will reduce the likelyhood of getting the
last card by almost 100% (because of the int()). Changing that 51 to
51.99 would help, as int(50.9) is still just 50.
