I switched to using Postimage.org for image hosting as Photobucket became a complete PITA to use.
The "Direct" link Photobucket offers will load all the PB crap instead of being the promised direct link.
However, you can edit it so that it does what you want.
http://i1206.photobucket.com/albums/bb450/par62003/.highres/IMG_4102.jpg is what they provide,
if you remove the "/.hires" section you get
http://i1206.photobucket.com/albums/bb450/par62003/IMG_4102.jpgYou can also derive it from the link you posted above, either by taking the first section (from = to & exclusive) and replacing the %3A with a colon or from the second half (from = to .html exclusive) and replacing the s1206 with i1206
paste that into the "insert image" button you get above the foc-u edit window and Robert's your mum's brother.
