Add custom share buttons

You may want to add share buttons for other services than "the big 3".

This is requested quite often, and can be achieved quite easily by creating a custom plugin that adds some jQuery code.

1. Go to Administration -> Plugins -> Local Files Editor -> Personal Plugin
2. Add this code:

<?php

add_event_handler('loc_end_picture', 'add_custom_share_buttons');
function add_custom_share_buttons() {
  global $template;

  //heredoc multiline, take care
  $script_content = <<<EOT

$(document).ready(function() {
  $('#theImageShareButtons>section').append('<a href="mailto:me@xy.net" title="Mail"><i class="fa fa-envelope"></a>');
})

EOT;
  $template->block_footer_script(array('require' => 'jquery'), $script_content);
}

?>```
The interesting part here is the ```<a href="mailto:me@xy.net" title="Mail"><i class="fa fa-envelope"></a>')```. You can paste any HTML code here from any service. The ```<i class="fa fa-envelope">```defines the icon to be shown. See http://fontawesome.io/icons/ for a full list of all icons.

3. Enable the Personal Plugin in **Administration->Plugins**
