MicroGal1.3
What does this do?
This adds a simple gallery on your page with support for the Fancybox lightbox and possibility of creation of KML files (geotagged pictures only). KML files can be shown using my gMapsKML plugin.
How do I use it?
Just insert the tag into your template/page like:
{microgal max_width="100" max_height="100" directory="pictures"}
{microgal max_width="100" max_height="100" directory="pictures" $takendate="YYYYMMDD"}
{microgal max_width="100" max_height="100" directory="pictures" gpsdata="true" kmlfile="pictures/pictures.kml"}
What parameters does it take?
-
(required)
max_width - Maximum width of the thumbnails generated.
-
(required)
max_height - Maximium height of the thumbnails generated..
-
(required)
directory - Directory containing the pictures for the gallery.
-
(optional)
takendate - Defaults to show all pictures in the directory given. To only show pictures for a specific date input the date as "YYYYMMDD".
-
(optional)
Coppermine - If using the Coppermine Gallery software set this to "true" to avoid showing Coppermine thumbnails in the gallery.
-
(optional)
gpsdata - Set this to true for geotagged pictures.
-
(optional - required if gpsdata is set to true)
kmlfile - Path and filename for KML file generation.
Other requirements?
The Fancybox script can be download from FancyApps.

CMSMadesimple is in a serious need of a proper gallery module supporting e.g. EXIF, IPTC and XMP tags. I have created this plugin mainly to support my needs and is still work in progress.
