styling resized images

The css classes from the original image are instead applied to the wrapping span. Make it so your selectors are no longer img specific, but instead specific to an img inside that selector, and you’ll be good to go.

In retrospect, applying those classes to the generated image would not have been too difficult and probably would not have broken anything, but I was attempting to replicate the proposed standard – a bit too vigorously, it seems. I’d add it as an update, but it would be a breaking change at this point. I may add it as an optional toggle in the admin later on.
