Panorado is an image viewer/browser for 360-degree picures. I offers a comfortable, innovative mouse-oriented control for panning and zooming created especially for panoramic pictures. The panoramic pictures can be viewed in flat, spherical, cylindrical, cubic or polar mode.
The interface fits perfect in the entire application and its components helps you navigate faster, view the images in full mode or thumbnails, etc. You can even burn the images to a CD or edit EXIF or IPTC formats. Not to mention the other special formats like + QTVR and GPS support.
Pluses: pan and zoom the image with the mouse; navigation bar; edit EXIF and IPTC format; GPS support
Drawbacks / flaws: nothing special when it comes to normal pictures;
In conclusion: A perfect fit for panoramic pictures.
