It would be nice to know how to resize it myself in case I want to change in the future.
There was a thread in clubhouse on avatars and resizing that had good info, but I use irfanview dot com to do mine. Supports most types and has other benefits, its free no time limits and no spy-junk and its a small program.
Edit' Clubhouse thread was (How do I convert bmp- jpg) but search for resize image and it should turn up some tips.
