On Chrome [latest release*], user avatars on submissions don't show up:

Here's the relevant HTML code:

Something about the "noLink" class is botchy; not sure what, but taking it out makes the image appear (though at the wrong size, 129x129, hiding the aura) and wrapping it an empty <a> tag will fix the size, like so:

Dunno if my pseudo-debugging helps, but there you go.


[*My Chrome version is Version 43.0.2357.65 m, and I'm on Win7, FWIW, but the issue has been happening for a little while now so I'm not sure which version the wonk happened, or if it was a site update, etc.]
