Ability to zoom out

[tomesposito]

I made this change a few months back but haven't made any changes since. This code is currently running in a production app.

I don't know what you've done but this script doesn't work for me.
Images can not be zoomed out but moved out of the visible area.
Maybe you can test your code again?
I have made my own version for zoom out now and will commit it after some more testing.
