From tfw2005 and the transformers 2007 movie blog
A pool of images related to the transformers movie has been created over at flickr. A total of 55 members and 271 images as of posting this article are in full force, showing pics from sketches of TF character designs to actual shots taken from movie shootings.
So far, we have sightings of a jet fighter canopy, chunks of a yellow transformer (believed to be Bumblebee), rumored chunks of megatron, prime running along what is thought to be desert sand, and many more. See for yourself at http://flickr.com/groups/transformersmovie/pool
