There's already an option for that which changes the images to links. Edit Options > Show Images (including attached images and images in IMG code)
Thanks Robin. I had forgotten about that one, but was thinking it would be great if it could be forum dependent. Like, MC you get images, so you can drool over the shoe pron, but say, in CE you get links and could click if it's a chart, etc. The other way to too global for what I was thinking. But thanks again for pointing it out to me.
