Dump PNGs for hosting on CDNs?

[dandv]

I was looking for 2-3 social network icons in PNG/JPG format to include in a transactional email template. Those things are notorious for bag browser support, so SVG was a no go, and even icon fonts weren't very promising in terms of support on odd email clients.

So I went looking for social media icons hosted on CDNJS, and only found https://cdnjs.com/libraries/webicons, which is really old school (rounded corners, gradients, the works).
