A quick note-to-self about how I managed to download a bunch of photos from an iPhone and convert them to.jpg on my laptop running Ubuntu 22.04. As opposed to Android phones, iPhones do not show up as a regular disk with easy access to the DCIM folder storing photos. Fortunately, Rapid Photo Downloader managed to launch the iPhone and find all the images. Unfortunately, all the files were stored as HEIC files, using the High Efficiency Image File Format.
