I'm having problems with the large images either linked to from a thumbnail or using PREV NEXT buttons.
Thumbnails are displaying perfectly OK.
However, when you click on a thumbnail for a large view the large image does not always appear (although the display box is OK) - No problem with the image info or the file image number.
If you do get the correct image, close and click on another new thumbnail, the previous, i.e. the same image is displayed again, with the new thumbnail image info. Clicking NEXT has a similar result with the image repeated. Continuing to press NEXT can result in retained image displaying in a whole browser page with no light box effect.
I've tried it with without turbo mode. Makes no difference.
