Where is the python mechanize cache/temp folder? How can I clear it? How can I retrieve files from it?

I'm on Ubuntu. I'd like to be able to retrieve images saved in my temp folder, and clear it, at will (or does mechanize not actually read images but rathe开发者_运维百科r just html?).

Mechanize doesn't retrieve images unless you specifically tell it to (on a one by one basis).
