An Australian programmer has devised a neat little Java-based app for browsing commons-tagged images. Once installed, the application displays a list of public domain image libraries. Click on one of the libraries, and a cloud of tags appears, along with tiny image thumbnails gridded up below. Hover over one of the tags, and links to other tags are displayed, and images labelled with those tags light up in the grid. Click on one of the images, and a larger version appears, with the option of viewing it in Flickr. This is a really interesting app that graphically shows the power of image tagging and offers and excellent way of searching a collection. Hopefully the programmer will add more libraries and more images in each library.
