You're not alone Eldorion
(nor you too Tinuviel). I only just recently figured out how to do it myself in Photoshop. But another easy way is to Google Free Avatars and then click on a link to a free resizing site. Some forums (but not this one) also require an online host. There are Free sites for that too. and some forums you can just down(up?)load from your own pc, or others directly from the resizing site (that's what I originally did for this forum).
The Leaky Cauldron required an online host (I forget which one I used now). But for Narniaweb and Aslan's Country, I was able to figure out how to resize with Photoshop (Finally
) and download directly from my computers picture files. But they usually have to be something like jpeg or gif files (I think). Sheeeeshk, we're "Nerds"
, you'd think we'd be better at this stuff
