Hey matey,
As far as the photos are concerned, have a look at something like
http://photobucket.com/ you simply sign up for a free account and then add the photos directly from your phone/tablet with their app, or upload them via the web site and then simply copy-n-paste the links into your posts.
My bonnet is single skinned, i think, but it is lovely and thick! and reenforced. I'll try and get some pics later if you'd like?
I was tunnel-less as well. With the old Sammio frame there was a very basic tunnel frame but just about everyone reworked that in some way. I'd already ordered a load of Mild Steel box section as i knew i'd want to fabricate "stuff" at some point, so it wasn't a problem and it did allow me to tailor the height exactly to me and the handbrake i chose.
I'm looking forward to seeing those photos as so far I've not seen two frames the same (Mike does improve things as he gets feedback, which is good!), so it'll be good to compare.
