HI! You can't edit your auction-- You are only able to "edit" before bids are placed, but you can "update". If you're on the app, go to the pencil at the top of your auction and click on that. From there you can add a "Note" and pics as well. Please add the expiration dates also. If you're on a laptop or pc you can just go to the listing and at the top there's an "UPDATE" button there too. THANX! WELCOME to Listia =_) Holler if you need any help hon :D
