To show images from another record, you can use the SharinPix Album component and set the AlbumID value to the recordID of the record you want to see.

To do so, you can either develop your own SharinPix Lightning Component and pass a specific value to the parameter, or more easily if you are not a developer, you can rely on a Flow implementation to do so. 

This flow can then be added to the Page record.

In our example, the result will be to display the images stored in the cases on which we have a lookup field set directly on the WorkOrder page record.

Here are the full explanation steps by steps on how to implement this : Display another record's album on a page record using a Flow (Admin-friendly)

To show images from related record you have 2 different SharinPix Lightning Components that you can use.

SharinPix Related Search

This component permits to configure in few clicks a SharinPix search on related records.

It takes a related list as a parameter and show all the images in the same Search result. Those results can be filtered on tags selection to only display some images.

In our example it can show in a tab named After Images all the images tagged as After in the WorkOrder Line Items related to a workorder.
And in a tab named Before images all the images tagged as Before.

SharinPix Related Record Albums
