On WikiLeaks, there are plenty of emails and information, but the only issue I had was that the images were contained as attachments that needed to be downloaded to view them. This makes viewing a large number images very tedious.
But luckily I realized that doing a site image search on Google actually fetches images WITHIN attachments! Thus saving plenty of time and giving the ability to view many images at once!
Try it for yourself!
Here is an example:

Try it yourself and let me know what you find!! :)
