Why are my photo card images blurry?


We are able to post photo cards via CONNOR NYC, but the images are showing up blurry, particularly on the iPad retina display. It seems as though twitter is resizing the image we provide to the sizes described at https://dev.twitter.com/docs/cards/types/photo-card , but these dimensions are a fraction of the available space, and being stretched to fill. Should we be providing specific image sizes to ensure that the image is not re-sized to dimensions smaller than the available space, and thus stretched to be blurry?
