We have gone to great measures to reduce the size of the media that is displayed on word pages and questions. School networks can be susceptible to network saturation when many students train concomitantly, a situation which strains bandwidth capacity. By compressing the media we have taken a great load off of the school networks.
We apologize for any graininess or fuzziness you might experience, but all images in their present compressed format should suffice for conveying their intended meaning. If you find something that is not working for you, however, please let us know the word and memlet with which you are having trouble.
