I didn’t see it there. I think I am just going to give up on sliders and just use single image page headers. I assume there is documentatiom on the optimal pixel dimension of images to be used as page headers?
It depends on the aspect ratio you’re going with. Most large images will work fine, but you will have parts of the corners cut off depending on the aspect ratio.
If you decide to go back to sliders, you should be able to contact them to ask about full screen options 🙂
