Tests
These tests redirect to the http image on github http://raw.github.com/blak3r/yaai/master/SugarModules/modules/Asterisk/include/call_transfer-blue.png
This test is interesting... because it works fine in a browser... but not when put into a SRC tag.
This fails because github attempts to host any "http" image on a CDN.

And the code that retreives the image apparently doesn't follow the redirects to get the ultimate image.
