Hi guys I'm looking to put some images on the Columbus in my S3 am I right in thinking all I need to do is transfer them from a USB key or is there any other ways ? Also when I have the images loaded onto the system is there any control ie have them cycle through etc? Thanks in advance

Correct. You can load images from any source - USB, SD card, DVD/CD, wirelessly connected media source etc.

You can manually swipe through or put it in slideshow mode whereby each image is displayed for a configurable amount of time.

The manual is actually quite good, particularly the app version, explains it very well.
