I saw that you uploaded the pictures. They are attached to the page, not in the image gallery. Currently the only way to get pictures into the image gallery is to upload them to the Flickr group and tag them with TheHurl and KA (And probably trebuchet as well). The image galleries here all automatically extract images from it, so the images show up on all relevant pages (if they have galleries) when given the correct tags. The Flickr group is at http://www.flickr.com/groups/thehurl/
If you want I can upload the images to it (I have an account and am all set up)
Your pictures are at http://thehurl.wikidot.com/local--files/trebuchettypes:king-arthur-ka/King_Arthur_ready_to_go (I had to remove the spaces in the name for some reason) and http://thehurl.wikidot.com/local--files/trebuchettypes:king-arthur-ka/King%20Artur%20release
The other picture seems to be missing somehow.
I'm going to add them to the page itself (using the images you uploaded) too because there are no better pictures to show the KA design.
I haven't got around to documenting the gallery editing process because no one else is editing this site. I'm glad to see that change! I will get some good instructions up soon, probably in the FAQ.
I'm glad you like my collection here. I'm constantly expanding it. Feel free to add to the text; the editor is the same as is used for these posts.
