I have infrequently seen that myself, if you refresh or hard refresh(CMD+Shift+R on Mac, Ctrl+Shift+F5 on Windows) the image sometimes shows up. I use uBlock and Privacy Badger and I assume they're the ultimate culprit haven't been able to pinpoint exactly what causes it. Hmmm, now I'm thinking it's uBlock since I use that as well. I was messing around with ScriptBlock and HTTPS Everywhere because I figured it was one those. Nope; just disabled uBlock for NSBB and reloaded several pages and still seeing the same thing for most Giphy gifs (though, oddly, the "glad to see me" one I just posted has worked fine the whole time). http://static.celebuzz.com/uploads/2015/05/Mad-Men-Bobby-Sad-Movies.gif
