Hi Keith.
In Photobucket click on the image you want, so that it shows in the slide viewer.
To the right you should see a box labeled " Links to Share ", Click on the "IMG" link and it should show "copied".
Return to your reply and on a new line "Right Click" and paste. You should get a long file deposited in that position.
Hit preview post and your post to that point should display as it would in the thread.
I hope this helps.
Jim
