Thanks for this script! I am running it on Windows and it seems to dump out when it hits some of the foreign characters in the description (?) column. Consequently, I am only able to download about 90 image files. Any way to make it decode those characters? Or this there another issue?

Thanks for the fix; I see what you did with the UTF-8 chars. However, the new code gives me the following error: AttributeError: 'dict' object has no attribute 'iteritems'. See details below.
