show/hide icons/images buttons

I would like to turn on the Command: Save still image (view larger proof) see attached.
I can find the button in my styles 1 but I can't figure out how to enable it in my product
can you help?

In your product configuration (Configure Generator area) you need to enable the Enable "Save still image" button option.
If you have it on already and by any chance you're still not seeing it, you might have it hidden from the CSS.
In that case look in your DirectCSS for userbuttons_stillimage, which is the ID of tha button's container
