[TECHNICAL SUPPORT] LPS-49461 The Profile Pictures of the Users is no longer displayed by Chat 

https://issues.liferay.com/browse/LPS-49461

See: https://github.com/natecavanaugh/liferay-plugins/pull/265#issuecomment-53236294

Regarding: "One solution I can possibly think of is to check to see if the portraitId is a number, and if so, create the URL, but if not, then use it as the URL.": I don't fully understand how the changes of main.js could break custom extensions of Chat. :-S (FYI: We also return the "portraitId" from ChatPollerProcessor.)

I also have modified chat-video.

Tibor
