Greg likes to send photos via email with Outlook and it always defaults to medium resolution. He wants to change it to a high resolution. How can he do that? Leo suggests trying to drag the image to the mail window and see if it downsizes. Another option is to avoid sending attachments altogether and send a link to the image online, like at Flickr or Google Photos. This is far more secure and he can have full resolution images online. In fact, Outlook will put the image inline at Microsoft OneDrive and then send a link.
