On a PC: Hover the mouse over the image you want and right click on the mouse. The menu this opens will offer 2 useful choices.
“Copy image” captures the image so you can paste it into an email or a document or a social media post.
“Save image as” lets you save the image as a jpg or png file with a name that you choose.
On a MAC, which doesn’t have the left and right click option on the mouse, highlight the image and then click on command c to copy and command v to paste.
