If you look up in the Navigation bar, next to Crossword, you will see a little link called "Photobucket".
This link, when clicked, will open a little popup with the photobucket login screen. If you login to your photobucket account from this popup, you will notice at the top is a dropdown menu with your albums. Select an album from your account, and you will see thumbnail images of all the pics in that album. Click one of the thumbnails, and the [img] code will be displayed near the bottom. Just click this [img] code to copy it, and then paste it into your post. No need to use the [img] button on the post screen for your photobucket images.
I did this because a lot of members are using photobucket for their images and this will make it a little easier because there is no need to open a new tab or window. If you do not use photobucket, you may want to reconsider.
