Just thought I woud remind everyone that Youtube, other forums, links to our own websites etc are not official sources for images. People place all kinds of rubbish on Youtube. Yes, I know it gets the worlds attention, but so many people use Photoshop and get creative there that, as a source for evidence, it is absolutely useless and sends us on wild goose chases.
We really need to get to the best possible source image in order to do any investigation of an anomaly because a compressed image of a compressed image of a compressed image is no good. It just does not have the raw detail we need and is likely to introduce more image artifacts.
