From the link you posted.
Right click on the photo, and from the box that appears select "properties"
A box will appear giving details of the photo.
Highlight the "address URL", and copy the text.
http://gallery.kitmaker.net/data/27610/DSCF0614_600x800_.jpgYou then need to type img at the beginning and /img at the end of that. These are called "image tags", and need to have [ and ] around them.
So its [image tag] address [/image tag]

Posting a picture from photobucket is even easier, as the IMG code is already shown and simply double clicking on that copies it, so its just a matter of pasting that onto your thread.

Hope this helps.
