Topic: Gallery 1.x to Simpleviewer(Admin) export
I always used Gallery 1.x: http://gallery.menalto.com/
I made a simple PHP export script to export albums from Gallery 1.x to SimpleViewer.
Customize settings in export.php: at least the gallery1.x and SV location
Put export.php on your webserver
Run export.php, choose an existing gallery from the dropdown and press export.
