Yes! Thank you for this.

installed on 3.6.2.. Instead of spoiler I called it hidden text and used hide as tags :)

Thanks!

First, make a button. Then go to your BB code for the spoiler, hit edit and scroll down to the part were it says "Button (optional)". That's where you put the path to the picture. ;)
