How do I get my gallery back to grid form from a slideshow form?

[AC Question]

I had to reset my HTC phone, and when I went to my gallery, it has this weird form. It's not like the grid. It's like in a slideshow type thing we're you can make slides and put music with it. I want to go back to the grid view! Can someone please explain to me how to get it back to grid mode!? I have tried everything I could do. Can someone tell me how do I get it back to grid mode?
