Donald, if you are a Photobucket user once you have your photos of choice uploaded there will be several links under each photo. Left click on the Direct link, it should turn blue.
Then go to your "Copy" option in your computer and click on it. When you are ready to add your photo in a thread or post here, go back to your options in your computer and click paste. The link to your photo should add directly in the reply box.
Next you will need to add the IMG tags at each end of the link, example:
[IMG]paste link here[/IMG]
Your desired photo should come up when using Photobucket and the direct link with these IMG tags.
I use Photobucket for most of my photos I add to forum messages. When I have several photos to add I keep Photobucket on a separate tab open and toggle between the site I am adding my photos and the album I have them uploaded to Photobucket on. That way I have Photobucket open for easy access to copy photos from or change to different albums quickly.
