The latest upgrade of Zenphoto Gallery has been published this week. Version 2.1 addresses some deficiencies in the realm of styling. A number of things were hardcoded earlier; in particular, image containers, captions and images themselves can now be styled on the options page. Other than that a small bug has been fixed and some code has been rearranged, preparing for release 3.0 which will introduce yet more flexible gallery style management.
One rather annoying bug remains since I was not able to figure out a solution. When using the dynamic preview introduced in 2.0, shortcode parameters with double quotes are lost somewhere between JQuery, WordPress and JQuery again. Hints leading towards a solution are appreciated.
