The Kiss Gallery Plugin is another Gallery allowing the admin to upload and categorise images from the backend. It displays the images using a lightbox.
The plugin can be found at: http://softly.dk/?CMSimple:Plugins:KissGallery (Appears to be Offline)

Sometime it happens that uploading of iimages (regardless if on a localhost or on the internet) returns the error message: “Wrong extension in”. You may find answer in Holger's post at:http://www.cmsimpleforum.com/viewtopic.php?f=12&t=451&p=2416&hilit=Wrong+extension+in#p2422
The same setting you need to make if working on a localhost.
