New social media icons

I’m playing around with the social media and tried to add my 500px account, what just don’t show up. G+, FB and Pinterest working fine. Is this because there is no icon provided?

Nope, no icon exists for that. Here is the list for social icons and other brands. If it’s in the list but it’s not in the theme you can let me know and I can give you the code you need to use it.

Icon is not available, I plussed the request for it.

Thanks for the hint.
