Change icon or add new button

Pls change the share icon for CopyInsteadOfShareImages with something more fitting if possible.

It would be even better if it had a dedicated button. <3

~~Sorry, I don't know how to do it. I tried but the shareButton is a 'View' type and not a 'MenuItem' type.~~

~~You are welcome to make a pull request if you know how.~~

Changed icon. Adding a button is beyond my knowledge.
