Hi Noel,
First of all thanks for this great plugin. I got it al working in a few minutes but I have a question about the plugin. Is it true that the plugin looks for the screen width and not the device with when serving the corresponding image?
I did a test with my site at blaze.io to see which image was served (they use an iPhone4 for that) and noticed that the image with a resolution of 768 x … was served in stead of the expected 320 x ….
So this got me thinking that the plugin uses the screen width instead of the device width. Because if it would use the device width it would serve a smaller image.
Am I right? And if you could device width be added to a future update of his plugin? That would make it even more awesome.
