Example of a Smugmug gallery hosted within a Wordpress entry
(note Lightbox display of large image)
For some time now, I've been using Smugmug galleries
combined with a hacked version of Adam Tow
's old WP-SmugMug plugin (hacked for Lightbox support) to show images within the Wordpress journal entries here on this site. Luckily, Adam has just updated his WP-SmugMug plugin
to support Lightbox 2 and a bunch of other options. I upgraded my install and had it working within minutes. Give it a try -- it's really good.
