I agree with Lana. Gisele, you're a beautiful young lady.
I don't know how or I would.
It really is quite simple.
1. Go to photobucket.com and create an account.
2. Click on the "Upload" button to upload your picture.
3. Find the picture you want to share in your Library.
4. Click on it. That should bring up a page with just the picture on it.
5. On the righthand side of the page, find the box that says "Links to share this photo". Click on the one that says "Direct". It will then say "Copied".
6. Now you can go back to the DIS to post. Do your normal reply, e.g. by hitting the "Post Reply" button.
7. In the "Reply to Thread" window, hit the little icon that looks like a postcard of a mountain. That's the "image" button. You'll get a prompt that says "Please enter the URL of your image". Just type ^V (that's a control-V), and it will paste your link.
8. Submit reply, and you're done!
HTH,
Bob
