No mate, they are all uploaded as single images... Assuming you are in Windoze - Right click on each individual image and go "Save Picture As" - they are all already named correctly so it's simply replacing them in your beecon image directory on the device and rejigging the pixel size of the image within the beecon settings.

If you're not in Windoze then not got a clue but they are separate images - I can upload as a zip if that helps?
