I am 100% sure that it has nothing to do with SRO. What you posted is a reference to an unavailable picture in Portable Network Graphics Format (png) that is stored in a Free Uploading Server (

Since SRO's Pictures are all stored in your computer, wouldn't in itself be suspicious? Of course, not unless you downloaded one software that you also use on your computer, and calls this picture(pk2 file perhaps?). While calling it, it simply can't, keeps repeating the call, and due to bad programming, probably fills up certain parts of your RAM which is also used by SRO. SRO can't execute, thus ---(((())))).
