Gallery View: Slide Show and Grid View SD631
Add slide show and grid view to galleryview for folders (not Book and Merchnadise details pages):
Slide Show: Add a slide show selector to galleryview with full screen, timer and left/right arrow controls.If there are videos (or any non-image content) in the folder, skip them.
Grid View: Add a grid selector and display a grid of thumbnails in galeryview. Open the image in a popup overlaying the grid/page when clicked. Close the popup via an "X" in the upper right of the image popup (and maybe left/right arrows on the popup?).
Image Download Note: Though it's worth noting that currently the gallery is showing the "large" scale size (max 768 pixels), not full original image. There's a pretty good argument to be made for loading the original size even if that's then being scaled down by CSS on the client side to fit the available width. That way download does get the full image, and it'll look better on high-pixel-density displays and giant monitors.
