Philipp: Just do an amount that doesn't start to overflow RC. It all varies on the wiki's activity - if it's quiet, do fewer images. If there is lots of activity, feel free to do 10 or so images.

There really isn't a set time, you just gotta keep checking RC and ask, "Is this starting to clog up?"
