If you like looking though photo galleries but sometimes find things clunky or cluttered, PicLens is a must have plugin for either Firefox or Safari. I’ve been using it since their first beta and have thoroughly enjoyed the ease it makes browsing photo galleries. I would absolutely recommend this to anyone who views photo galleries on popular websites like Flickr, Picasaweb, or even Google image search. Download this plugin now!
How it works: PicLens takes all the available images on a page and goes full screen with a black background. Not only does it look great but it allows you to navigate using the arrow keys. Believe me when I say it can really speed up the browsing process. To read more on how PicLens works, read this users review.
