Rough website design ideas

 left and right through gallery top pannel hides from view when not hovered over, each button has its own hover over and darkens when hovered and text lightens.

right and left semi circles for navigating within the folder, left gray pane for website navigation(home, blog, contact, etc) top left pale gray panel says menu (hovering over this brings the darker gray box into view from the edge or fades in)
add another box at the top to navigate up a folder to look at other types of gallery
