Display the MiniSlide Show on your Gallery.
MiniSlide Show is a flash-based slideshow with support for Gallery 3. This module will allow you to integrate the slideshow into your existing Gallery theme.
***Caution: If you remove permissions for everybody to view full size images for an album serving a remote slideshow, the slideshow will stop working on sites using it. ***
This module may be downloaded from the Gallery forums here.
To install, extract the "minislideshow" folder from the zip file into your Gallery 3 modules folder. Afterwards log into your Gallery web site as an administrator and activate the module in the Admin -> Modules menu. If the RSS module is not active, you can activate that while you're on this screen as well as MiniSlide Show requires this module in order to function properly (you may also wish to edit the code for the RSS module as well).
Note that this module does not include the actual MiniSlide Show program. You must download and install it to your web server separately from here.
After everything is installed, you will have an Admin -> Settings -> MiniSlide Show settings menu option. Go to this screen to tell Gallery where the MiniSlide Show was installed, and to configure any additional settings. Afterwards you will have a slideshow link on your album and photo pages that users may click on to view the slideshow.
