Picasa API Issues

Im trying to do a basic upload to my Picasa album. I’ve tried the example in the documentation and one found on another site. Both fail with no error at the last step, a call to

insertPhotoEntry()

Zend is set up correctly and pathing is correct. I know this because the test script they provide comes back all tests ok.

Any ideas why? Below is the test script
