You need to go in and edit your bio to put a pic and/or text. If your pic was  hosted somewhere else it is gone as stated in the Front Page article (link attached in the first post) so you'll just need to edit and add what you want on your Artist Bio tab. Then all your other stuff like any freestuff items you've uploaded, tutorials, blogs are on the second tab "Artist Input" . Your Featured Image and more images by you that you selected in your gallery options along with fav artists and fav images is on the "Gallery" tab.  The store tab contains your favorite vendors and a sampling of your store products if you have any. The Contact page is for someone to sitemail you.

Hope this helps.
