I have been reading the Google App Engine documentation to learn how to use the Images Python API. I asked several questions in the appropriate forums but so far there were no relevant answers. I was wondering if an expert here help me out with this. I put the entire script here http://pastebin.com/dxWJPNCa

These are the questions that I asked in StackOverflow and Google groups for GAE:

http://groups.google.com/group/google-appengine/browse_thread/thread/3c55ed3461e6395b?hl=en#

These are the sample code that I am trying to copy:
