Dreamwidth style system discussion

Ah! That's the user link, not generally referred to as the contextual popup, but the link itself that shows the popup. That's definitely more clear - and more difficult in general to pin down. The bottom border you see on those links isn't actually on the image. It's on the entire link, which includes the image. Think of the entire linking item like a box. There's a border at the bottom. Inside the box there's an image and the text link. You'd have to take the border off the entire thing in that specific case, is that what you want?

As far as the user links in your actual entry, perhaps something could be done about that in general. I don't have your style up, and my firefox is being wonky to look at it, but maybe something similar to the following might do the trick and override your link style:

img[src*="feed.png"], img[src*="community.png"], img[src*="user.png"] {border-bottom: none; text-decoration: none;}

You can always try border-bottom: 0px too if none doesn't work. Or just a general img a tag with a border: none. That would take the border off all images unless otherwise specified.
