From the arena submission page;
We won't accept image submissions from sites not on this list:
* photobucket.com
* imageshack.com
* deviantart.com
* tinypic.com
* piczo.com
* xanga.com
* flickr.com
* picturetrail.com
* webshots.com
* snapfish.com
* shutterfly.com
* slide.com
* kodakgallery.com
* geocities.com
So, dev art IS supported. Right click the image, click view image info, and copy the location. You can also save it from Dev art and upload it to photobucket which is what I prefer to do, because I've had problems with deviant art pictures that I've linked turning up blank.
To answer the other question, I have one- but I don't really have anything recent there aside from that phoenix I drew for the pictionary game. Everything else is pretty old aside from some sketches.
