loading over https issue with use of WP_PLUGIN_URL

When using an https plugin to load all page elements over https the wp-easy-gallery elements do not load via https. This appears to be due to the fact you are using an outdated method of calling the location of the plugin files (WP_PLUGIN_URL). When in fact you should be using plugins_ur(). See https://wordpress.org/ideas/topic/wp_plugin_url-doesnt-take-ssl-into-account

Therefore my page is shown as not secured because of the 2 javascript files being loaded via http.
/wp-content/plugins/wp-easy-gallery/js/jquery.prettyPhoto.js?ver=4.3
/wp-content/plugins/wp-easy-gallery/js/EasyGalleryLoader_hideSocial.js?ver=4.3

Can you please fix this ASAP? Or let me know how I can work around it?

Thanks
