Fuzzy image display on new content type I'm having issues on our Drupal 7 site. We have created a new content type that includes a hero image. The problem is that full sized images that we upload aren't displayed on the page (despite calling for "Original image" in the manage display settings. 



Instead, the page is displaying the image in Drupal's "large" image style, then scaling up on the page and creating a blurry image.

Here's a test page: https://claremontmckdev.prod.acquia-sites.com/content/history-0
Based on the markup on your test page reflecting an html5  element and the code snippet calling for a "picture_sizes_formatter", I suspect your site has the Picture and Breakpoints module) installed which automatically serve images based on predefined/configured breakpoints.  

Go to the Picture Mappings configuration page Config >
 Media > Picture Mappings (/admin/config/media/picture) to examine existing mappings and add new ones.


You should be able to add a new picture mapping for a wider breakpoint to serve the original image, thus limiting serving the large image to a narrower desktop viewport.

Once you've added an additional mapping (and possibly a wide breakpoint), don't forget to clear the caches before reloading your test page.
