Or try this:

It's always a little tricky to bring your pitures into a forum the first time.
If you are using photobucket or similar web space for further photos you only have to
- right click at every photo in your web browser
- choose "Link-Adresse Kopieren" (in German Firefox) or a similar option in your favorite web browser which only copies the link.
- go back to the forum.
- press the "Img" button above
- and fill in the copied web address by "right click" and "paste / einfügen" or just press "ctrl / strg" and "v" - But I think that is what you know already...
If something went wrong you also can click the "edit" button under each already released post and change things afterwards.
Happy Posting!
