Hello, friend @oaldamster, 😄😇😄😇

I have been directly linking to photos on http://unsplash.com (permitted by their terms of service), and also using https://imgsafe.org and Google drive.

One other suggestion for your readers - it is really fairly inexpensive to lease a little web space (actually, a lot of web space) from some ISPs... for just a few dollars a month, you can put up your own website and host a lot of images in a sub-directory... Just google "website hosting" and you'll find endless suppliers... ;)
