I wanted to post pics in such a way that they would be enlargeable. Read one post that said to do it as an attachment....didn't work, can't click to enlarge. Would like to delete that post!! Is there a way to test how a pic will look BEFORE actually posting it? And how do you delete a post that you don't want to be there? Help! I have 8 pics (can do it in two posts if necessary) that range from 337 kb to 743 kb. Just posted that post in Pictures under "test for loading pics".
