Welcome to The Norfolk Broads Forum
This is THE Worlds Largest Forum devoted to the Norfolk Broads, here you can discuss issues about the Norfolk Broads. Or just somewhere to chat with others interested in the Norfolk Broads area.
At the bottom of the message box, under the clever buttons and the font option, there's "File Attachement."
Click on "Browse" and locate the JPEG that you want to post. (I tried once to fill in "File Attachment" by hand, and failed... but that could have been due to a bug in my finger driver.)
