Show an image in a form after selecting an option in a drop-down

I have a form where a rep selects a drop-down choice for brick colors, for example. I wanted to be able to 'show' a small image of the currently selected choice on that form (prior to submit). If the rep chooses a different brick, the new image would update. The drop-down choice is a connected record to the bricks object. A brick object record contains Name & Image, with Name as the exposed field for the connection.

How would I display the image for the Chosen Name in the form? (I did see that the details page can display the image chosen, but that is AFTER a submission takes place.)

Thank you for any help in this direction.

Best regards!
