I've seen this popping up a lot lately. Users have been putting images inside blockquotes to add the darker border around the image so it doesn't look like the image "blends into the background" and is easier to tell it's an image.
How would I ever know that this image isn't part of the normal content without the border!? Ok, bad example (if you hate unicorns!!!). This happens a lot more often on meta when posting screenshots of the website.
It doesn't bother me so much, so I don't really care. But being the HTML semantics freak I am, I don't like the idea of putting images inside blockquotes just to create a border effect. So I'm curious how much of a problem people think this is, and if images should have a border applied to them to make them stand out. Where does everyone stand on this?
