my server is crashing after adding this mood. somehow stop responding with 100% server load. I notticed that also images that visible only to admin is showing in similat images.
do your images have proper keywords or descriptions? The mod as it is uses keywords. If there are none, the main loop will not terminate.
I'm using this mod with a database of nearly 8000 images and extensive metadata without problems. Maybe your gallery is much bigger? I can't guarantee the reliability of this mod for any number of images ...
