you can try this link, as well

CreateWindow calls CreateWindowEx, with lParam = 0

I want to upload an avatar. What size/format is allowed for it?

[dedndave]

i use 130x130
not sure if there is a format requirement, but i think i used a PNG
i think there is a file size limit, but i forget what it is
as long as you don't try to use a hi-def BMP, you'll probably be alright - lol

I've tried to upload 209x209 jpeg but received an error "picture is either too large or is not an avatar"

looks like you got it   
i was going to say - use Paint or something to convert it to a PNG file

[GoneFishing]

Yes, I did 
It was Paint I used to convert the picture
