v3.1.5 has been submitted for approval:
FIXES
fixed issue with cleanup tasks, which removes old plugin version of application, not running
modification to the 'Convert images to links within quotes' functionality to resolve a rare issue where 1 of multiple images with exactly the same name/url etc is left visible, while all others are hidden.
NEW
Added a 'Disable display of full size image' setting to allow admins to control behaviour of lightbox image display for guests, applied if images are not being hidden for guests
If enabled, the image displayed in the lightbox will be the thumbnailed version of the original file (i.e. the image actually seen by the guest when viewing the content)
Option to 'Display login prompt in the lightbox' is also available, allowing the admin to show a login prompt instead of the thumbnailed image
CHANGES
No other functional changes
Tested and confirmed working on IPS 4.6.0 (Beta)
