I am getting ready to update to the latest version of ZC. In the process I noticed my image cache was out of control. I have Image Handler 3 loaded and have clicked "Clear Image Cache" but didnt see any kind of change. I don't see an Image Handler3 folder in the bmz_cache folder so maybe it's not in use. However, in the bmz_cache folder there are folders 0-8 and a-f. Why are these here?
