<aside> 📌 Use a Template column to paste the code and replace PHOTO for the picture column your prefere most. Use a Rich Text with this template column in the tab you want to replace the edit button for a picture.

<aside> 💡 Once the Edit button still works, my suggestion is to use Users spreadsheet for this tab and filter by email is signed-in user.
