Display the uploaded image on the detail page

Hello folks,

I recently completed an interesting requirement and wanted to share the following information with you.

Requirement: The object record should have a detail page button, and the user should be able to upload the image file to that record. The uploaded image file should appear on the record details page.

Solution: I created a visualforce page where the user can upload an image to Salesforce’s content file system. The main goal now is to display the uploaded image file on the record detail page. I did this by creating a rich text field and inserting a file download URL in the tag.

Q. Where we can find the ‘ContentDownloadUrl ‘ after file upload?

Ans- The ContentDistribution: Represents information about sharing a document externally. We need to insert the ContentDistribution object record after ContentVersion insertionYou will receive the ‘ContentDownloadUrl’ for that file after inserting the CD (ContentDistribution) record. More information about ContentDistribution can be found in the Salesforce doc here.

Create a detail page button on the Account object, as shown below:


Find the VF and Apex code for this implementation below:

Visualforce page:

<!-- Name: UploadImages
Decription: Upload images in files object and show them on richtex field on record.
