All that you have to do is scroll down when you're replying to something and in the 'Additional Options' list, find the button where it says, 'Manage Attachments'. Click on that and something should pop up. Click on where it says 'Browse' next to some white boxes, and it should open up all of your image files. Choose which one you want to attach, click on it, and once it's listed, click 'Close This Window'. Then it should have attached, and you can then make your post and it should show an attachment! ... I hope that wasn't too confusing, lol. ^_^; I know nothing about computers so I can't explain this kind of stuff all too well.
