Ones that you create, for boards where you do things like that . I'm not sure how to post a human avatar, can someone please tell me how?

Problem is that its an avatar i made but isn't an actual one with a username.

You'll have to save the picture then upload it to a site like tinypic, photobucket, imageshack, etc.

If you created the avatar on a site like SubetaHQ, then you can usually right-click and save the image that way, then upload it. If you created the avatar in your wardrobe, however, you need to take a screencap: ctrl+PrintScreen, paste it into a program like Paint, crop away the excess, and save it as a PNG. THEN upload it (I use tinyPic).

Hope that helps :)

OR if you created it in your wardrobe, Save the avatar, then click "load saved avatars" (or whatever it says) and rightclick to save from there and the image is higher quality, then upload THAT to an imagesite :)

That is what I do and they always look awesome.
