It took me a while to figure out how to post pictures directly into posts, rather than just adding a URL, and I've worked in IT for the last 11 years!!!!
I always cut and paste the
from the third box down under the picture, and then change the
to lower case, like Randie says, and you end up with a picture in your post! It took me a while to work that one out!
Best of luck.
