It is becoming the norm now for content on the web to have come from a source other than the page you are looking at. A recent search pulled up this interesting collection of maps in an old blog post. The image that first caught my eye was this one:
but no source is mentioned. Google’s ‘similar’ image search pretty much failed with this example (see results here) getting distracted by the bold green colours.
The image is linked to http://marion.sanap.org.za/MapPrinceEdward3d.jpg. Browsing around the website for Marion Island we can find the page which the image was taken from. However, even then it is not clear what the source of the image is. Searching on both Bing and Google provides no extra hints.
One of the more interesting tools out there for web forensics is TinEye. With this example, no results showed up, however with another example from the original blog post, 6 other locations were discovered for the image. TinEye finds images online which are related in a more direct manner (e.g. identical images, cropped images, etc.)
