Responsive Lightbox / Fancybox Pro / Images disappeared

All the images have disappeared, 2nd time this has done this, they all show up when using the free lightbox, SwipeBox, prettyPhoto, FancyBox, Nivo Lightbox,Image Lightbox
TosRUs

but not on lightbox pro, they are there in the source code but don’t show up

The gallery is within a custom shortcode that i have set up, seems strange that all the other lightboxs show the images

I notice that when I delete the image from the media gallery and then upload fresh copy of the image, that image shows, but see as i have lots of images it’s a oain in the butt to keep doing this everytime i want to add a new gallery.

Any ideas on what to try would be appreciated from trhe Developer would be appreciated
