I'm a new user and impressed with this site -- generally easy to use, and lots of great participation, help and information. I can't figure out how to post an attachment. I want to post a photo that I've taken of a lens and have a question about. I see in my posting rules that "You may not post attachments." I can't find anything in the FAQs that addresses this. I've tried inserting a link to photos on a web site, but I cannot get this to work either. Is there a set of instructions? Are newbies limited in what they can do for, say, the first 30 days? Thanks!
