CS Gallery Manager is an application for Community Server 2007
FEATURES:
Upload a bunch of files at one time
Manage the existing files on the galleries you have access to.
Create and delete albums/categories.
Update the names and descriptions of the images.
INSTALLATION (read before download):
If you have a Community Server installation and have access to its folders, you can make use of this tool 
.
Part 1: The new Gallery Service:
Your Community Server installation has a Gallery Service that provides a basic set of methods to retrieve information about the galleries contained on it. This web service could not be used with CS Gallery Manager since it needs advanced functions that the default installation doesn't have. This is why a custom web service is included with CS Gallery Manager: the Extended Gallery Service.
Part 2: The Application itself:
CS Gallery Manager comes in a Windows Installation Package file (*.msi). This is the client-side application and runs on (every?) Windows system (requires .NET Framework 2.0+). This is the application that really manages the galleries, connecting to the server or servers where you installed the included Extender Gallery Manager.
DOWNLOAD:
You can download CS Gallery Manager in a compressed file that also contains the Extended Gallery Service. It's all that you need for it to work.
This file can be downloaded clicking the button that says "Descargar" or this link: http://www.superjmn.com/files/folders/3345/download.aspx
Known problems:
When adding a new category, you have to manually choose its parent.
The tag selector works but it is not very elegant at the moment.
It's not possible to edit categories.
Thanks to Dave Burke and Duncan Menzies for their help. Without you, the Extended Gallery Service wouldn't have been possible.
