edit: Chipped: Your board already has several hosted files on the top, so why couldn't you do this one? You've got music, animated gifs as well as pictures. You have to be hosting all that stuff.
Yes, you have to host the file and put in that little tiny bit of html code. That's exactly correct.
People already can customize the appearance of this whole site, choosing all of their background color and menu colors and such. They don't need a premier subscription to do that, either. You'd be overriding those individual choices by setting a different background color at the top of your board. Just thought I'd mention that, in case you didn't know there already are a lot of customization options here.
Most ISPs that we use to log onto online, give people some online storage space. It's just a matter of knowing how to access it peroperly for the hostiing of files. I figured out how to do it with earthlink broadband, aol offers a lot of space per ID, too. Most ISPs offer it and there also used to be many free hosting sites on the Internet. They might be gone now, but until you get Matt or Bob to program the feature you want, maybe you can poke around and find another way to do it.
By the way, Matt, it's nice that so much is available for the free access. I appreciate that.
