This:

I can’t use db.key() function in the html file

is not true. You can use any functions or methods that don’t take arguments in a template. So, as thebjorn pointed out in the comment, this would work fine:

img_id="{{ message.key }}"

because the template language would call the key() method and then convert it to string for output.
