Welcome to the Airtable community!
There isn’t a way to customize the built in email notification. However, you can build you own email notification using an automation that triggers off the new form submission and uses a “Send email” action. You could either include the images at attachments, or use some complex formula fields to include the images as html images.
On the other hand, I find it easier to be permanently logged into my Airtable account, I click the link at the bottom of the notification email to view the record in Airtable, and it takes me directly to the record, where I can see the attachments.
