Recommend me a good photo album web script
 

Someone asked for something to generate quizzes a few months ago, so I figured I would take a stab and ask something similar. I've crawled the web a bit to no avail. I'm looking for a photo album script to add to a web page I'm building. What I require in it is straightforward:

• HTML or PHP preferred. I know next to nothing about JS but I am open-minded :)
• Must support multiple albums/folders
• Must be easily integrated into the design and style of my site
• Must not require any extensive coding each time I want to add new images. Some sort of back-end interface would be nice
• Must be capable of displaying EXIF data
• If I could add captions to images, that would be nice, but not a must

So, computer wizards, what do you have for me? Thanks a bunch in advance!
