Looks like some of my images become broken after Photon was activated.
As an example: http://www.automoblog.net/2012/10/23/2013-lexus-gs350-review/
The first and fourth images in the article show as broken.
Let's use the first image as the example. The original image being called is http://www.automoblog.net/wp-content/uploads/2012/10/2013-Lexus-GS-350-front-side-view-623x389.jpeg - that works fine. When I deactivate Photon, it also displays fine. But when Photon is activated, it shows that it's broken. When I try to view image (http://i2.wp.com/www.automoblog.net/wp-content/uploads/2012/10/2013-Lexus-GS-350-front-side-view.jpeg?resize=623%2C389) it says "We cannot complete this request, remote data was invalid"
