Running upload.py with the -simulate argument makes no difference. Files are uploaded to the wiki regardless of -simulate meaning "do not write anything to the wiki".

I tested it on a wiki when it allowed uploads. I've also tested it on a test wiki where uploads are not enabled, so it pops an error with a traceback, that will be more meaningful:

$ python pwb.py upload.py -simulate -family:test-1-23 TestFile.png test
> The filename on the target wiki will default to: TestFile.png
> Enter a better name, or press enter to accept: 
> The suggested description is:
> test
> Do you want to change this description? ([y]es, [N]o) 
> Uploading file to test-1-23:es via API....
