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.
