Photos from USB will not upload to iCloud because of JPG (But they have jpg extension)
3600+ photos on USB... Made Album in iCloud and tried both drag & upload cloud button. 1500 upload but the others do not. Some statement that only jpg can be uploaded. BUT these photos have the .jpg extension. They will open in preview so I exported one to the desktop with jpg added and Still doesn't like these photos. The photos are from and old iPhone. I've tried multiple times and called Apple help. Still cannot upload these photos. Maybe they were corrupted (not sure). Why can they open in preview but not upload to iCloud? Any suggestions? (also have 2 TB of iCloud and fast internet)
