O2 in the UK has plugged the security hole after it caused a storm of people angry with the service after it had been revealed that photos sent by MMS can be found with a simple Google search.

MMS messages are sent to its web server if the recipient does not have a compatible phone - like the iPhone 3G - and the recipient will receive a URL so that they can view the image themselves. But it had been discovered it could be accessed by a simple InURL search on Google.

It has taken down the server, with people attempting to view the site are now redirected to an Apache server error. The leak - many containing images of children - was embarrassing to the company, as it also runs a site that is dedicated to protecting children online.
