Easiest-Image-Gallery is a project mainly written in ..., it's free.
Just mixing Pixlie, Gallerific, easyslider ... and stuff.
Easiest Image Gallery - überhaupt
Ever wanted a full-customizable image gallery with multiple albums? Eig lets you create a galleries by just putting files on your webserver.
Save the pictures of an album in subfolders (so far I just tried numeric names g) of "galleries" and eig* will worry about the rest.
Optional you can claim proper headers, subheaders and descriptions in galleries/texts.php for your albums. The image title, image description and any copyright statements that may arise will be read from the meta data of the image - so you can use your favorite photo-viewer to manage them e.g. aperture.
Pretty easy - huh?
Eig is made by mixing Pixlie, Galleriffic and Easyslider!
