Hi Jordy, awesome plugin! I've been able to figure out uploading the correct image sizes and all, and it looks like everything is set in the Retina dashboard. I'm using the client-side method. However, when I turn on Debug I can't tell if it's working or not.
I've read from the plugin FAQs that I should "see" the larger images, but how exactly? I'm using Firefox and when I click "View image info" with debug on, it shows the image sizes as the smaller, non-retina, sizes without the @2x before the extension. Is this the expected behavior with debug on? What should I be seeing to make sure it's working?
I'm sure this is answered somewhere, but I'm not clear on what to expect when checking if Debug is working.
