No database needed, works with any web space. You must set the values in variables.js and create thumbnails in advance. Thumbnails displayed in 4 rows and 5 columns, or in 1 row below web size images (height 480 pixels), full size images shown upon request. Minimal interface, no ads. Edit the source code for your own needs. Option to write comments to the images and describe the collection. See the gallery on my site for a working sample album.
