I have used ImageCapture (standard on a mac), PhotoSync (not free, but it's cross-platform), and the SanDisk iXpand drive. (with its app, plugs into the phone, backs up photos. Unplug it and the other end of it is USB to share with a computer). AirDrop works with macs. (Always have a friend with a mac and v/v) Apparently, iXpand is very slow if your photos are in iCloud, because it has to download them in order to back them up. Use it with on-phone photos. I recall that it backs up the photos incrementally. There may be other apps that web-serve the photos. If so, you can use wget or curl to bulk copy them.
