Gallery Maker
=head1 SYNOPSIS
Gallery Maker
=head1 DESCRIPTION
Gallery Maker is a Gimp plugin.It generates an HTML file from all pictures it finds in a designed path.A thumbnail is generated from each picture with a desired global scale or X or Y fixed...This tool will hopefully help batch conversions from photo albums for instance as you can add copyright notice on source picture but also adjust brightness/contrast or give polar rotations ....
Convention used here is the following : All pictures converted is c<name> ....Relative thumbnail is m<name>
Note : This plugin only processes JPG pictures.
