I tested many photo gallery tools looking for a best tool that will suit our needs, from photo animation, slide show, article images integration...to creative portfolio display, just to name a few. I found Phoca Gallery, tested and there functionality are impressive. Installation is straight forward just like any other Joomla component. It took me a little more time to get acquainted. The Phoca Gallery demo site is very instructive and well organized, the explaination is simple and provide example for each of the plugin functions.
Strongly recommend to give good try. I will impresse you... A+++ to the Phoca team.
