Welcome Geoffrey, good to have you onboard! FrJohn
I don't think images can be imported directly from the web (if they can, I haven't figured it out yet). The only way I've discovered so far is for the image to be on the local machine I'm using. What I usually do when I want an image from the web which is licensed for our use is to download it to the desktop and then upload it to OrthodoxWiki from there.
