Thank you for this plugin.
It was working fine until 3.6.1 and now once an image post is clicked, the screen goes dark and the popup waits a long while before appearing, or sometimes does not appear at all until you click around.
After further testing it seems to be limited to IE10, 9 and 8. Works ok in Firefox, Chrome and Safari and iphone5.
Could you advise please: http://dev.devongolfcaptains.org.uk/devon-golf-captains-v-shropshire-hereford-captains-2/
