It won't let you edit the auction details itself but there should be an "update" button that lets you add pics. I don't think it stops letting you add pics no matter how much time is left, but I could be wrong. I'm just kind of hesitant about bidding because you're so new and I have a LOT of credits to bid on this
I am. I'm trying to establish good standings, thanks and I plan on putting up more Games s so I will make sure to include an open case pic in future listing, thanks for the info
