Pintotess, if you have created a photobucket account, then log into your account and there should be a big green button that says "upload images"
Click the button, and go through your hardrive to where your pictures are stored, and click them (hit control while you click them to select multiple photos to upload)
Once the pictures are saved on your photobucket account, underneath each picture should be a set of links to post. Copy the "direct link" url, then click the image button at the top of your text box here, when you post or reply (its a little yellow box with what looks like a mountain and moon or something in the picture) paste the url in the line, and hit enter. Wala, picture posted. :)
In order to post a video, you will need to upload it to youtube. Once your video is loaded, it will give you the link to where your video is stored. Just copy and paste the url into your text box in a reply/post.
