Not a solution, but marked as such because it’s the best available option @Mindy_Belcher - as far as I’m aware, Public Links only show task name, due date, and assignee.
No other information can be shared in a public link.
If it’s mission-critical to your business, this can be done with a custom integration to Airtable or any other tool that can display photos with a public link. You can use Unito, Zapier, or Make.com to accomplish this, but it will require a custom setup. If you have a developer or low-code expert on your team, they can help you with this.
FYI: My integrations team can build this. Let us know if you decide you’d like to get professional help.
