Hey Bill I am going to try to explain this the best I can; if you or anyone else gets lost like I often do gimme a call.
Posting Pics using the img tag: (All of this is based on the assumption you have a Shutterfly or photo sharing website pulled up on another tab (window) with the pictures that you want to post)
Once you have typed whatever you have to say about your adventure, hit enter to go to the next line and type [ img ] but with no spaces. Then go over to your Shutterfly window/tab and double click on the picture to make it larger. Right click on the picture, then left click on properties. A box will appear, look down and you will see Address (URL). Highlight and copy the entire link starting with http then be sure to click on cancel on the bottom of the window. Next go back to your post and paste the link directly next to [ img ] you already typed. Once the link is pasted go to the end of that link and type [ /img ] Remember there should be absolutely no spaces in the brackets - I just put those there to show you because without spaces the tag won't show up.
Then voila! after you click post you should have a pic posted.
I am going to do exactly what I just explained

once your pic is up if you want to add some text about the picture just hit enter and start typing on the next line. Then add more pics if you want to by hitting enter and repeating the above process.
