I was cruising around the internet and I came upon the website of this art/religion Journal called IMAGES. I think it might be pretty helpful for us, so I already asked them to send us a few copies and maybe some backissues so that we could get some real concrete Ideas. The Journals should be here in a week or so, but until that feel free to browse around the website. The website is more of a teaser for the print Journal, it seems, so there isn't that much real information on there, but it can be helpful nonetheless.
Here is a link to the Journal's Website
