Welcome aboard, Steve. 
Glad to have another inmate in the asylum. I think you'll enjoy your time here...it's a pretty good group, no raging attitudes that I've come across, and most everybody's happy to share ideas and techniques. Ask away, when you've got questions.
For posting photos in your threads, you'll need to put them up on one of the hosting sites first. (I use Postimage, which is free, but there are quite a few around with different features and storage limits.)
Once 'hosted,' copy the link the site supplies...then paste it into your thread here using the little picture icon above (insert/edit image), and it should drop right in. It's hard to be more specific because different sites use slightly different terms and such, but the hosting site link may be labled 'share' or may even specify forums. Once you've done it a couple times it'll become second nature.
Any questions or observations, just sing right out.
(BTW, I think you'll find many of us here are in your same relative age bracket. "Old enough to know better," as the old saying goes. 
)
Cheers
