uploading photos - display image

Hi. What's the best way, or site to use, to display a still image in a post. I don't subscribe to ANY photo sites of any kind, and don't intend to - so this is a one-off kind of thing.

Sorry - ignore this - saw that the new forum software allowed uploads
But this site worked as well I think, after a little research: Postimage.io — free image hosting / image upload — Postimage.io
