Do you mean you just want to show the thumbnail of still images but not the panoramic images? If you add "Thumbnail" component in your virtual tour skin, I am afraid that all the small shots will be shown. If you just want to some of them to be listed as thumbnails, you may make it in this way: 1.Add "StillImage" in your virtual tour skin. 2.In the right column, select an image and an action for it. The action setting will enable you to link the thumbnail to any panorama or still image. Though it may take you some time, I believe it can be a solution for you.
