how to get a pic

I want a picture of a gnarwhal 2 holiday but it says the avatar is to big?
how do I get a profile image???

you resize it
there are several online websites who propose to resize a picture

There are a lot of free image editing packages, such as or the GIMP that can easily resize a pic. Get one. is probably the more straight forward package to get. Both are very capable and worth having.
