If you have a lot of images/videos to post to Media Gallery, you have several options:

JUPLOAD Media
Remote Gallery
FTP Media

JUPLOAD Media Method

JULOAD is the easiest because all it requires is that you go to the JUPLOAD tab.

Remote Gallery Method

Remote Gallery uses a third-party helper client application that you can download from http://gallery.menalto.com/wiki/Gallery_Remote. Once you download it, you will need to configure the parameters for ADAMSSCOUTING.ORG:

Alias: adamsscouting.org
Username: The username you use to login to adamsscouting.org
Password: The password you use to login to adamsscouting.org
Gallery Type: Geeklog
Gallery Login URL: users.php?loginname=$USERNAME$&passwd=$PASSWORD$
Gallery Module URL: mediagallery/$GALLERYFILE$

After you configure that, you should be able to login.

FTP Media Method

You will need to request an FTP user account from the webmaster. At which time you can upload via FTP and then do an import. This is the best method if you have a lot of files and or a lot of large files.
