You save it on microsoft paint and upload the file to a photo upload site and then copy the link to your profile picture. That is how it is done through dokuga. I think you can upload the picture to your deviant through 'submit'.
That's the long version, to hotlink a image from another site, or you can follow Hairann's tute here:
Posting Banners in your Profile
I did a long-winded version using the IMG BB board tags if you want to link an image from like Photobucket. That's here:
Hotlinking Banner Images from Photobucket
Either or will get the same result.

P.S: Hairann's one is easier though.
