yo i fixed the thumbs not working. if you want to create a thumbnail of a picture on the site that links to the full size of it, just type [ thumb artnumber ] without the spaces. so for example, you could just type [ thumb 2015 ] (without spaces)

The reason the image didn't work was because of the automatic link creator. i'll see if i can have it detect if it's within an img tag and then not create a link.
