MediaBrowser is a great tool for viewing images/photos on your disk or in your folders. All images in a given directory are displayed in a thumbnail view that can be zoomed out to show many or zoomed into to show just a few. You can easily organize your images in folders and use MediaBrowser to view them.
Slideshows are a snap with MediaBrowser because once you have a folder's contents in view, just click "Slideshow..." and you're ready to go. With this unique slideshow feature, you may view multiple slides at once.
