As requested, I created a small virtual gallery of 8 images.
Changes to the previous galleries:
fallback to png: when the default image-1.jpg cannot be found, the tour will try to load image-1.png. this allows for some transparent images to be displayed inside the gallery
pano support: if the image that is being clicked has a pano associated to it, the pano will be opened on click. Pano images should be in the /images/panos/ directory and have the same name as the image (image-1.jpg, image-2.jpg, ...). The pano must be in equirectangular format as krpano will try to load it as sphere.
