You can now display uploaded images and signatures directly inside OpnForm email notifications, so recipients can review visual submissions without opening every file in a separate tab.

Enable Display uploaded images inline in any email integration where Include submission data is turned on. Supported GIF, JPEG, and PNG files up to 6 MB each appear vertically in the email and remain clickable through their secure file links.

If an image is too large, unsupported, unavailable, or would make the email too large, the notification is still sent with a clear image icon and filename link instead. Other uploaded files now use the same readable filename treatment, so recipients no longer see a long OpnForm API URL.

How to use it

• Open a form and select Integrations.

• Create or edit an Email Notification integration.

• Turn on Include submission data.

• Turn on Display uploaded images inline.

• Save the integration.

Good to know

• The option is configured per email integration and disabled by default.

• GIF, JPEG, and PNG files can be embedded up to 6 MB each.

• Multiple images and signatures are displayed vertically.

• Selected PDF attachments take priority if the email reaches its total attachment-size limit.

• Images that cannot be embedded fall back to readable, secure filename links without blocking the email.

• An embedded image remains in the recipient's mailbox after delivery, even if its external file link later expires.
