It used to be that you would have to email everybody a photo you wanted them to see. No longer do we need to bung up the system with photos and just as well since they can be quite big.
No, put them in your G Drive or save them to your “Photos” if you have a Google account and then share them. In that way the people you want to view the photo can get at it without you sending it. What’s more you can control if they can download, edit or send it on.
Photos and G Drive are Apps on your Android phone and they are also available on your PC or Mac by clicking on the little dice symbol when you have your Gmail open.
