Jackie is based in Denmark, and when he did a search for 'Laptop' on google.co.uk he got the usual results, with three image results shown under the top three paid listings (see pic).
I've tried to replicate this from the UK - but all I get is the standard Google results.
We had two theories -
1 - they are the top image results - except that they aren't - they don't appear in the top 5 pages of image results
2 - that they're ads - except that they don't bill themselves as ads, and whle two of them click through to merchant pages, the third goes through to a student's page
On reflection I think that they're examples of image integration - but the images have been chosen by Google - they're not the top results for the page. Which leads me to think that this is an engineering test. Also, this only works on 'laptop' - nothing else we can think of gives any picture results.
