KurtK, I never congratulated you on the boat.
Congrats on finding a unique, extremely well-cared for boat
KennyK posted a link with great info.
Figured I would go a little deeper on image posting...
There are many posts here about image posting.
When I searched the topic, many seemed overcomplicated (for my short attention span anyway)
Here are the basics – if you need more details, just ask, many will answer.
1. Create a folder on your computer; “C:/picture” is an example folder location/name
2. Transfer (upload) the pics from your digital camera to the C:/picture folder
3. Create an account on a free image hosting site.
A web search will find many image hosting sites.
My example is
http://photobucket.com/ .
I have no affiliation with photobucket aside from good service and ease of use.
(creating a profile on an image hosting site isn’t any harder than creating a babc profile)
4. When the account is created, follow the steps in red.

Along with pasting the IMG Code text link in a new post or reply,
you can also paste the IMG link in your sig block profile.
That image will come up on every post.
I may be wrong, but I think the sig block pics are expected to be a certain size
(small, per board rules).
Have fun boating & posting pics.
