I can't find an option to delete some images I posted. I'm sure I've done this in the past, but where is it?

Click on the image. At the top of the page in the center you will see in bright orange against a black background "Admin - Editor Options". Click on it and you'll get an orange bar that goes all the way across. On the far right click "Delete this Page". Note that the page is merely marked for deletion and won't actually go away until Matt gets around to it which is usually within 24 hours if not faster.

Ha! Guess what the problem was? Of course, I'd gone to "Admin - Editor Options", but I couldn't find "Delete This Page" anywhere. But once you told me where it was supposed to be, I realized the problem was the width of my laptop screen. I couldn't see the far right side of the orange bar till I hid my bookmarks sidebar. Thanks!
