If you upload a photo from your computer to a post and perhaps make a mistake and have picked the wrong photo when it appears BEFORE you have clicked on the Post icon/button, how do you delete that photo before posting to the forum? There doesn't seem to be a "review" of what you intend to post BEFORE it gets listed on the forum so you can make a change OR am I missing something. I know you can edit once you've posted but how to edit before it is posted? Thanks.
