Gallery is a slick web based photo album written using PHP. With Gallery you can easily create and maintain albums of photos via an intuitive interface. Photo management includes automatic thumbnail creation, image resizing, rotation, ordering, captioning, searching and more. Albums can have read, write and caption permissions per individual authenticated user for an additional level of privacy. Give accounts to your friends and family and let them upload and manage their own photos on your website!
I have also installed Gallery on my server. It is a very powerful, yet easy to use photo gallery tool that makes it very easy to upload and display images on the web. I plan to install it over at Buckman later today. Several teachers are looking for an easier method of batch uploading images and with its large list of features, Gallery should do everything we would want a web photo tool to do.
