FS#8335, with some changes discussed on IRC:

Browse source 
Resize can be turned off (on by default). This will not look good if
covers are larger than the desired size.

Album title config: show at top or bottom, or hide.

Center margin is actual distance, in pixels, between center slide and
adjacent slides. Defaults are now set to show three slides to each side.
