Add a 500px.com Social Icon

Currently SmugMug does not have a way to enter a social icon / link to 500px.com. What we can do instead, is to add your 500px.com link into your "Custom" URL in the Social Settings, and then change the standard paperclip link icon into the 500px.com icon. To do that, add the following.

For standard 500px icon:

/* Change the custom link icon to the 500px */
.sm-fonticon-Link:before {
  content: '\E20A' !important;
}

For Circular 500px icon:

/* Change the custom link icon to the 500px */
.sm-fonticon-LinkCircle:before {
  content: '\E260' !important
}

For Square 500px icon:

/* Change the custom link icon to the 500px */
.sm-fonticon-LinkSquare:before {
  content: '\E25F' !important
}
