Hello @Jean_Pierre_Traets,

I like that when you mouse over a lookup item you trigger the popup window with the related details.  
This is useful for an image gallery for quickly peeping at the details of the image-item you are viewing.  
Imagine to combine the features of the image-column (thumbnail & lightbox gallery) and the lookup column (mouse over details).

Unfortunately lookup items don’t display the thumbnail.  
To work-around this, I’ve implemented the following 2-tables system:

1. Image catalogue: used for tagging and commenting the file images (1 image per row)
2. Image grid-gallery: a single cell table used to lookup the items from the catalogue, using this trick

**Current issues:**

1. being it a lookup, you get the **rounded frame** around the thumbnail, wasting precious space.
2. Even if you have all the image-items loaded into a single cell, **the lightbox is independent** for each image, which means: when you click on an image you don’t get the useful bottom menu-gallery or the side arrows to turn to the next image-item.
3. I can display **only simple text** in the pop up window (like tags), but having problem adding buttons or links (ie to load the proper detail view of the image-item), json is not fun to work with 😃
4. thumbnails sometime **fail to load** and I have to use a button with a refresh action on the catalogue.
5. kind of slow overall.
