I have an iPhone 6 I canโt find the way to downsize them. It saves them as jpeg format.
Open with Photos, do an edit to resize/crop (as recommended by Mopars) then save the new pic.
Jpeg format is accepted but size does matter. You may have to "crop" several times. till you hit the sweet spot.
If you don't have photos, open with gallery.
Most forgot, 3 pics to a page on average.
