Well, you prevailed! Lovely shots, too. (They don't look particularly sideways though they may be!)
I've come to believe that it's easier using a photo hosting site than putting the photos up here. So I modified my blurb to the following:
This is a way to add photos to your post:
Once your photos are on a photo hosting site such as Imgur.com, select the image, then Control-click (Mac) or Right-click (Windows) and choose copy image location. Now paste the URL into the box that pops up under IMG in the compose reply window of the thread.
If you want to use the site's album (images tend to be smaller than hosting site's size)
1.) Login
2.) Go to My Account (may have hit Home button first) and mouse down to Album.
3.) Choose Upload Picture (navigate to photo you've given a sensible name to), be sure to then hit Upload.
4.) Go back to Album, click on thumbnail to open full size image. Right click (Windows); Control Click (Mac) and select "copy image location" (its URL).
5.) Return to your reply window in the thread and click on the IMG button at the top of the compose window.
7.) Paste the image location into the window and click OK.
