Ok, first of all, I was mistaken about the renaming. If you upload an image, as you are doing, rather than providing a link to an image, the system does re-name it to "userpus ghetty.jpg". So that part is normal. To clear the cache, In NS it's: Edit/Preferences/Advanced/Cache/ then: "Clear Memory Cache' & "Clear Disk Cache" I still think there might be a problem with your user name. Send me another Private Message and see if I can respond by clicking.
