You can upload to the gallery here at BF and then tell us they are there. Or you can put them on a site like imgur.com and just write the sharing link in your message. If the spam filter balks at the link, then you have to make it not look like a URL and most of us can figure out how to make it work again. Usually remove the https:// and maybe put a space on either side of any period.
It might be a test to separate the lambs! <grin> But most every high traffic website I've been on in the last dozen or more years does this for spam protection.
Welcome to BF!
