The page is loaded and all images displayed. I disabled the Spoof Referrer option in uMatrix and then blacklisted: - assets.tumblr.com - media.tumblr.com (which includes 78.media.tumblr.com and 68.media.tumblr.com) - static.tumblr.com - assets.pinterest.com - g.twimg.com and was able to reproduce the issue. The other resources (www.tumblr.com, px.srvcs.tumblr.com, platform.twitter.com, www.google-analytics.com, connect.facebook.net) didn't help. We can ignore the tp-content domains (tumblr.com and pinterest.com) since the breakage also occurs with the standard list. So in conclusion: - twimg.com - Disconnect = [tp-social]

Added uMatrix results.

Broken images.
