Wow! How do you tell it to? I've been complaining about this for ages because we have tons of photos that get high ranked.
Oops, never mind. Finally found it after posting. So THAT's what 'web' and 'image' filters mean.
I just realized though that that only applies to whether they SEARCHED for web vs images. For instance if an image comes up in that row of images under a text search which occasionally come up on the 3rd row of text results, and they click on it, WMT still shows the .jpg using the web filter. It also appears to report the avg rank from an image search.
