On photo bucket click on your picture. On the right side you will see a group of links. Click on the last one, "IMG", and you will see "copied" appear. Then go to your THO message, press "enter" to give you a new line in your message and do a "paste". If you then select "preview" at the bottom of the message screen you will be able to see both your message and your picture. Edit as required, I usually spell check and post.
Welcome aboard Jack! Glad to have a new Reelfoot maker.
