Mike, I have made a new instruction for how to use Photobucket on the CCC. Other photosites will work in a similar way, possible slightly different actions in the first step.
First go to your Photobucket account.

Next go to the CCC and the thread you want to post in.




After this, hit SUBMIT, or repeat to add more than one photo to a post.
Hopefully it will work for you as well.
Enjoy the beauty of Customizing
