Thanks Derek. I've looked at the properties of Bexhillian's avatar which is a little smaller than mine. Changing mine to the same size made no difference, it still only displays as a static picture. I've now tried experimenting, just on my PC, and found that reducing the size of the file or reducing the display size to anything less than its original 480x480 pixels results in a static picture. Since the max avatar size is 140x140 pixels it looks like this particular file cannot be made to work on this forum - at least, not by me.Another member (possibly Bexhillian) has a perpetual motion goldfish, perhaps he could give you the size and settings used for his avatar.
