As far as I understood ZU isn't blocking the art section for him, his Internet blocker is.
How are you going to check the thread for replies if you can't get to the art section? If you can view the
Synthesis of Imagery you'd probably be better off putting them there, since they're created digitally.
Edit: Wait, I just read you'd be able to get there with a URL. Oh well. SoI would still probably be a better/easier choice.
