We are leaving Conga Composer and are implementing Docusign Gen in our org.
In our current use case, users can upload photos (.jpg , .png, etc) to the Files on the Work Order object. Then we generate a work order using Conga Composer. The document generator grabs the Work Order Line Items and displays them in a table. Below the table, it shows ALL photos that attached to the related record. Conga does this by allowing us to Query the related images and display them in a dynamic table.
I saw in the documentation where you can use XML and a field based URL to display images but we are looking for something that dynamically displays the images without our end users (non-admins) needing to populate any fields with URLs. There current experience is using Salesforce UI to upload the photos they want on the document.
