"The internet is going to be a might plain looking place without any graphics..."
My understanding is that this vulnerability is in WMF graphics, which are an oddball format that only Winblows supports.
Turn off WMF support.
My understanding is that, because of the way Windows core components operate, the exploit can be enclosed in any sort of image file--JPEG or GIF, for example.
That won't protect you -- Windows recognizes any file with a certain header within the file as a WMF and processes it accordingly even if the file name doesn't end in ".WMF".
