If anyone ever does need some scaffolding pics (both good and bad examples) a site I have used for free images is eLCOSH Images which has some pretty decent shots you can use.

Another one to consider is safety_photo_links which has a decent selction again. Might be woth the forum asking to share a link with his site?
