PicLens is a Firefox addon that turns Flickr sets, Google image searches, Facebook photo albums, and many other sets of pictures into beautiful photo walls.
Once you’ve added PicLens to Firefox, photo sets that you view as a photo wall will display a small Play button when you hover over them. Click on the play button to go to a full-screen visualisation of the photos.
Alternately, you can click on the blue PicLens button, in the top-right corner of the Firefox window next to the loading indicator. From there you can type in a search term and get the top results from your favorite photo search engine in the photo wall view.
Once you’re in the photo wall mode, you can click on one of the photos to zoom in on it. Double click it to zoom to full screen. Scroll with your mouse wheel to see fewer or more photos at a time. Drag the blue box at the bottom of the screen to move along the photo wall.
It’s beautiful and smooth as silk. You absolutely have to try this to see how awesome it is.
