In the past you could select revise listing, pull up and by the phtos there was an EDIT option, only thing I see now is a trash can. Yes, I can add morre pictures. I want to crop ones already there

I just need to click on the photo itself to bring up the editing tools.  I have heard a few sellers report they had better success if they double-clicked or right-clicked, but I haven't needed to.  Try just clicking in the center of the image and you should see the editing tools pop up.
