Maybe I can help.
1 - Go to your photobucket album and bring up the picture you want to view.
2 - Right click on the picture and pick Properties.
3 - In the Properties window, hold your left mouse down and drag it over the URL next to the word "Address: ". After you have the entire URL highlighted, right-click on the highlighted text and click on Copy.
4 - Now, go to the browser you have open where you are entering your post. Right below the window where you type in your post, there's a section called "Instant UBB Code". Click on the word Image in that box.
5 - That will bring up a little pop-up window and will ask you to enter the complete URL for the image you want to show. Delete the "http://" that it already put in the box for you, and then right click in the box and click on Paste. That will paste the URL of your photo in the box.
6 - Click on OK. You will now see the URL in your post window wrapped with
tags around the URL.
Your photo should now show up in your post.
