Ceases to work when duplicate image is found

[DedrichVonDorn]

Script fails when trying to write a duplicate filename. Here is the error

FAIL Image is a duplicate of 400.jpg, not saving 2100.jpg

Traceback (most recent call last):

I think it's just coincidence that it fails at that point, as it works fine for me. The most important information is this:

RuntimeError: can't start new thread

Number of threads specified in the script is probably too much for your system. Try to lower the number of threads on line 7

This issue will be resolved after merging PR#7

I believe this might have been fixed in most recent commit. Let us know if not.
