actually on Option #2 if you use the Image Code provided with Photobucket you can simply paste the code directly into the message. No need to use the Image Url drop down as the code is already added by Photobucket.
Smokin, you can save the Photobucket images from within a message. Then the issue would be adding the image directly into the post and deleting the imade code. My guess is that is probably not possible. I can see you being completely overwhelmed with adding images.
