If you don't feel like resizing any of your pictures to the tiny 50x50 size, why not find some on the net?!  

  Just go onto Google Images, and type in-avatars 50x50.  I did, and came up with a few different sites.  That's where I got my pumpkin from!  

  Here's one site to get you started!

PS.  If you use one, let me know.  I'd love to see it!
