Mak, Trotter and Larry have the power I don't but I am all for keeping the img tag's off in the virus area for the simple reasons of "The executable image exploit" or as I like to call it get pwned 6 ways to sunday by web 2.0 faggitory.
I just turned on Img Tags. Quotes tags should work no problem. They were not touched at all. Img tags are staying off in the Virus area. There is no need to have them on there along with pretty much anything but Code and Quote tags. As it is called a Virus area for a reason.
