Forum:Pywikipedia bot, regex page moves?

I've recently started using the pywikipediabot, and I was wondering if there is a way to move all images with extension .PNG to .png, using regex. (I know I'll need admin rights for the bot, that shouldn't be a problem.) Quartic ~ insanity is a virtue  |  Talk  19:36, September 15, 2009 (UTC)
