I'm surprised this hasn't been requested, but a gallery or image field for custom fields needs to be created. We are looking to use custom objects for our automotive clients but we need the ability to showcase vehicle images attached to each VIN/item.

For example, a gallery so our sales team can sort through the images taken by our detail team. We use a fairly popular automotive CRM system and looking to make the switch to HL for more flexibility with our automation and AI. One of those holdups is getting inventory into HL. For custom objects, I feel like this is a must in regard to inventory.
