Your pasting the url to the photobucket page, not the url for the image itself. When you hover the mouse over the thumbnail in photobucket, the pop up menu shows the url, and even an IMG tag that you can just cut and paste. The other option in Firefox is to look at the image full size, right click on it and copy the image location. Other browsers have the same functionality.
