I've got 2 Problems:
I have the 0.4 Version of this plugin installed.
I tested the Plugin Safari and Chrome on my Mid 2012 Macbook Pro Retina.
In Chrome it works well but in Safari it's broken.
Safari shows only the original, non retina files.
Does the Plugin only Support Chrome?
I wanted to test with Firefox, but Firefox does not support retina anyway.
A site with retina support:
My second problem:
On my website http://www.alteziegelei.org is a slider. (nivo slider)
I wanted to use the plugin too after creating @2x picture in the backend, the plugin removes the height and width tags of the image so it looks like a retina pic on a non retina screen.
But everything is ok if I look at the slider with a non retina screen.
