login dialog in random thread?

[deathbug74]

received an unexpected login dialog box in this thread.

looking at the page source, it looks related to something someone linked (or tried to link). only recurs on THAT thread.

thoughts?

Poster tried to post a music cover art image from www.mixcrate.com.
The URL posted...
http://cdn2.mixcrate.com/img/ugc/covers/2/1/2176962_l.jpg?v=319201416

falls in line with a typical URL for images on that site
http://cdn3.mixcrate.com/img/ugc/covers/2/6/266863_l.jpg?v=208201354

Likely a permissions issue that is intentional.

FWIW, it shows up as a broken image in my brower(Chrome).
