Lol! Wash your mouth out!
No need to lower your standards (no disrespect to the Stone Pages!), Groat - posting a pic is dead easy - just go to the relevant page (eg http://www.themodernantiquarian.com/site/23/avebury.html) and click on the "Add" dropdown. Then select (you guessed it) "Add an image". On the next screen, browse to the location of the image on your hard drive, enter a credit and description, click "Submit", et voila! Follow the guidelines at the right of that page and you'll not go far wrong... :)
Or pop it on Flickr and add a link to it in your forum post. :)
