I completely understand your frustration. I just learned how to do it, myself. You have to copy the whole line next to img. Then I pasted it to my post. I did not use the image button up top. I hope this helps.
to post the photos here. Open them in photobucket and copy the url (address) to clipboard. click on the Img button here in the forum you will see Img twice with brackets aroung each one. paste the url of the photo from your clipboard between the bracketed img's
