It took me several minutes to figure out what they wanted. Remembered that my Avatar was on another board. Went there, right clicked on it, hit "view image", hit "save image", hit the "browse" button and the bottom of the Avatar page, up popped the save page from my PC, found the "saved" image, double clicked on it, and presto, it showed up in the "blank" space at the top of the Avatar page. Hit the [forget which one now] button, and bingo, it is now there.

OFC-takes me a while, but I get there
