You may download the photos later by connecting your aircraft to Hangar 360 and looking in the library to see if there are any thumbnails waiting to be downloaded. Occasionally, there could be a hiccup with the app and photos will not be recognized for copy.
This can also happen if you remove the SD card from your aircraft before copying the photos from your capture.
If you still have the original 23 photos on your SD card, you may stitch them yourself. We cannot recommend a stitching software at this time, but if you Google stitching software, you will find many suitable choices.
