Question: Getting dimensions and pixels of loaded image
Hi!

I'm just started to experiment with Sketch and love the approach. I can't find documentation for working with images, so maybe I'm missing something?

Is there a way to load an image inside a sketch (I'm using `load-resource` at the moment) and then get its dimensions to use inside the sketch? 

And is there a way to work with the pixel data from the image (like in Processing or similar)?

Thank you!
