The customer was using the "save_post" hook to automatically fill lat/lon coordinates from a Toolset address type field into another custom field, but the values were not becoming available for new posts.
The customer asked if it is possible to create a slider gallery with Toolset that shows the main image on top and also shows images in the lightbox.
Solution:
Explained that Toolset's slider block offers both these requirements, individually, but not together, so it will require a third-party slider/gallery plugin.
