Just a reminder, after editing an image you should tag it from "untranslated" to "untranslated_original". Also, I'm not sure if you really need to link to the translated version from the untrans as people normally just search "translated + artist"
I didn't realize that's what that tag is for, but it does make sense. I've only seen a very few images that actually have it, though. As long as people know that's what that tag means, a link isn't strictly necessary, but otherwise it really is pretty helpful.
I think it only really pops up for recent pictures, and only if they've got hard edits of them already...so in comparison to the untranslated/unedited stuff it's a pretty small ratio
