While we should never have missing files in normal circumstances, it would be nice to catch that exception and keep running the reprocess_photos command

This is accomplished pretty easily by editing management/commands/reprocess_photos.py:

and changing:

val.reprocess(save=False, force_reprocess=force)

to:

try:
val.reprocess(save=False, force_reprocess=force)
except IOError:
print "File not found: %s. Could not reprocess image for model: %s"%(val.url, model)
