Hi Guenter,
You were simply using the wrong code from the photobucket site (I believe you were using the thumbnail code). I have edited your post above using the: -
(once you've clicked on the image you want, a grey navigation menu will show on the top edge of the photo) Share > Post to web site > Get link code > IMG for bulletin boards & forums (navigation route on Photobucket)
And then cut and paste the code from the
Full size box.
I hope that helps
