Hey Choo-Choo,
If the whole photobucket thing is too complicated, then try our other (much simpler) method of posting picture. Above the text box that you type in to post a message you will see a link that says "Add image to post". Simply click that link and select your file. Once you select your image file select "Upload It" and then it will be posted to your message automatically. Give it a try and let me know if you still have troubles! Remember that bigger pictures will take longer to upload.
Thanks!
Chad
