after a not so simple fix, i was able to use graphic converter to change the database to the two forms of each pic that were needed. I then simply made two versions of the script, batchConvert_A.py and batchConvert_B.py. The results are currently being run, and I assume that it will take a good portion of the evening.

But this part of the script is completed. Next I will need to start looking at pitch height... most likely on monday afternoon.

here is the code for batchConvert_B.py ... although i should note that this blogger doesnt seem to care for indents much.
