Note: I have moved this thread to the appropriate forum. Please make sure that you select the appropriate topic AS WELL as the appropriate forum to post the comment thread in. I know it is a minor PITA to have to select the topic on two different drop-downs (the comment drop down is located in the "Comments" menu below the posting window) and I am trying to find a way to only have to select it in one place. Until then, you must set this manually in both places or your comment thread will end up in a moderation forum until a moderator can move it to the appropriate forum for you.
That is why you were having trouble.
Also, I recommend that the max size image that you display inline is 550px. You can, of course, link to a larger image. Anything larger than 550px currently breaks the layout. This will be corrected very soon and displaying images too large will simply be cut the end off instead of allow it to break out of its content space.
I look forward to seeing more of this project.
