Hello and Happy New Year.

On our facebook page called "stafford remembered" we had a picture that was posted innocently, someone then asked what the car was in front of the double decker bus.. this then got hundreds of posts with different answers on different websites until someone came up with this link below..

My questions are, how did it reveal the number plates that were missing from the original picture?

How were you able to zoom in so much?, i tried it with different pictures from our same site but to no avail.they just looked the same..:(

Thank you very much in advance for your help.

Hi There,

The person used the zoom system to generate a zoom of the original picture.
The person took the original picture to generate the website.

There are few different size, so it tooks the biggest one to be able to generate the zoomed pic. So in fact the big pictures is already available online.

Also if you look at the big picture, the plates are not hidden

Hope it helps

thank you

Yes, that is correct.

Seadragon or Deep Zoom (which uses) are ways to zoom into photos which are already high resolution (and which might otherwise be too large to download quickly or navigate smoothly).

They do not make more information out of low resolution images (which simply don't contain more information).

George Birbillis below suggests using reverse image search to find higher resolution copies of a given image.

TinEye was the first website to offer this and years later Google Images copied it.

Bing Images can look for more sizes of an image it already knows about, but doesn't allow you to input a link to an online image or upload one from your computer to look for a higher resolution copy online.

Here are a couple of videos which help explain how Seadragon works:

Facebook makes a lower resolution I think when you post images to it

Also, given a lower resolution image posted somewhere, you may have luck with Bing or Google image search (they both allow image upload I think) finding a bigger resolution of that same image. Then you just post its url to and you have a zoomable version
