Yeah, I could see how that'd suck up both the bandwidth for server that runs these forums and eat up storage space too. Graphics require a lot of space compared to text. The URL tag problably makes more sense than allowing IMG tags.
And hey, if anyone is looking for a free place to upload your pics there are probably still some free webhosts out there. I think <A HREF="http://www.geocities.com" target="_new">Geocities</A> even still does that. (Gee I hope so, since my website is still stuck there. I really have to download all of my site again in case Geocities ever goes down.) There's also probably <A HREF="http://www.bravenet.com" target="_new">Bravenet</A>. I know that they used to let people upload images to free accounts. I haven't checked lately though. But if they've kept growing like they were a few years back they probably even offer full free webhosting by now.
So if you just need a place to upload your pics you could do something like that and just use URL tags to show them off in posts here.
