Bill,
To use photobucket...go to
Photobucket and sign up for a free account. Once you've done that, then upload your pictures to photobucket. You can do them one at at time, or as many as 19 at a time!
Once they're uploaded you'll get a screen that looks like this:
All you need to do then is copy the circled IMG file and paste it into your post that you're typing and hit submit...it's that easy!
