Open the picture you want to edit, in the blue multi line box below the picture look at the last line it says "Admin Options: Edit photo", click that and it's self explanetory what you can do.

In this edit section you can also replace a picture with a different one if that's part of why you want to delete a picture, otherwise do as Matt said. The only "problem" with replacing an existing picture is that while you can change the pic, the title, the description, the view count will stay the same as it was when you started the edit. If that doesn't bother you then it's a go.
