If I hide image information and the photo navigation 'arrows' by pressing the 'information button'. They then disappears. However, when I click on the 'Expand Gallery' button, then they appear again. I don't want them to appear after clicking on the 'Expand Gallery' button, if they are as in this case hided before clicking on the 'Expand Gallery' button.

What do I need to do to solve this?

Thanks.
