If you have a Facebook account, you can use that to host pictures. Just right click on the image and select “Copy Image Address”. Also, if you have a picture that you don’t won’t to post on Facebook for others to see, when you post it just select “Only Me”. You can still use the link to post elsewhere.
Thank you very much for the advice, though I don’t use Facebook. I haven’t had to look at how to do this in so long, I have to ask for advice...:)
