Can anyone give me advice about how I can mass delete select images from my wiki? I have pywikibot but I'm fairly new to it and find it confusing. I tried following the instructions I could find as best as I could but can't get it to work. When I try to use the delete.py script, it gives me the error "Unable to execute script because no generator was defined." Can anyone tell me what I'm doing wrong here? Thanks in advance.
