=head1 NAME

galleryImport.pl - Import media into a Gallery asset from various sources.

=head1 SYNOPSIS

 perl galleryImport.pl --configFile=www.example.com.conf --fromAssetId=XXXXXXXXXXXXXXXXXXXXXX --toId=XXXXXXXXXXXXXXXXXXXXXX

 perl galleryImport.pl --help

=head1 DESCRIPTION

This WebGUI utility script imports files from the filesystem, and other assets
into a Gallery asset. It automatically generates thumbnails and metadata just
as if the files were uploaded through the user interface.

Files with JPG, JPEG, GIF, and PNG extensions are supported.

The thumbnails are created using L<Image::Magick> for image transformations.

Exactly one --from* and exactly one --to* parameter are required.

=over

=item B<--configFile filename>

Specify the config file name of the site you wish to perform this import on.

=item B<--fromAssetId assetId>

Specify the asset id of an asset to import the files from. The asset type is
automatically discerned.

The supported asset types are Collaboration System, Thread, and Folder.

=item B<--fromAssetUrl url>

Specify the URL of an asset to import the files from. The asset type is
automatically discerned. The B<url> is the Asset URL parameter, not a fully 
qualified URL.

The supported asset types are Collaboration System, Thread, and Folder.

=item B<--fromPath path>

Specify the absolute B<path> to a folder containing folders images and other
folders with images. The folder name is used to create an album name, and the
files contained in the folder are added as photos in the folder.

=item B<--help>

Shows this documentation, then exits.

=item B<--tags keyword keyword keyword>

Attach keyword tags to the photos and albums created. One to 10 keywords may 
be specified. You may specify multi-word tags by wrapping them in quotes.

Eg: --tags=green old "very expensive"

=item B<--toId assetId>

Specify the B<assetId> of the Gallery to create albums in.

=item B<--toUrl url>

Specify the B<url> of the Gallery to create albums in. The URL is the asset
URL parameter of the Gallery, and not the fully qualified URL.
