What is the actual function of that app?
it will show images via folders. more like a file system for images only. Can slideshow the whole folder or selected images. THen plug in the HDMI or AV cable to display it on a Tv.
You can also use PlayTo and view all your images into a Xbox360 and it can display them via slideshow to show off to the family. Other DNLA devices should be able to do slideshow as well.
