Macbook OS 10.14.5 can't open jpg attachments sent in Mail
Sometimes when receiving jpgs in Mail written under neath is "downloading" but I can't open them no how and have asked senders to send again differently which usually works. Recently this happened with photos sent from a Samsung phone which I assume is Android. I can't seem to drag them out of the email to the desktop to open with Preview.. I'd like to solve this once and for all. HELP!
