Overlay images not available for displaying

From semantic-mediawiki.org

I know this is old, but I just ran across this problem myself. On Windows servers, the href uses "%3A" instead of ":". Changing

var title = image.attr( 'href' ).split( encodedNsText + ':' ), to var title = image.attr( 'href' ).split( encodedNsText + '%3A' ),

on line 96 of ext.srf.gallery.overlay.js worked for me.
