Other image-gallery effects worth checking out are: jQuery FANCY BOX; Lightbox JS v2.0 by Lokesh Dhakar; and JAS-Gallery by Robert Nyman. These are very complicated jQuery/JavaScript/JAS scripts that we have not been able to implement here. For our attempts so far see illustration/indexfancyBox.html and indexLightbox.html.
This sample demo page is illustration/indexCSS.html. See also indexCol.html (which does not use rows), index.htm (which features a Javascript slideshow), indexTable.html (experimenting with image sizing and positioning), and indexCSS.html (another CSS layout).
