How can I share my photos online?

Old Geek wants to share his sketches with friends. What's the best option? Leo says that uploading images to Google Photos is a great option. He can upload scans or photos of his sketches to Google Photos and then share links to his images to anyone he wants. He can also use a sharable folder and then send the link to the folder for them to enjoy. He could also use Flickr and Facebook.
