gPhoto is a universal, free GTK+ application that will allow
downloading, saving, and manipulation of images from most
digital camera models or from the local harddrive.

gPhoto has a basic command line interface, which is handy,
if you want to set up a web camera, and use gphoto in a
script, e.g. with Perl/PHP.

gPhoto sports a new HTML engine, that lets you create special
gallery "themes" (HTML with special tags) for publishing images
on the web.

gPhoto source code is available from the gphoto web site www.gphoto.org
at http://gphoto.org/download.html.
