How SharePoint Handles Images

The Rules - SharePoint Header Images

The Rules - SharePoint Header / Banner Images

You’ll get the best results using images proportioned near 16:9

  • They’ll be cropped rather than scaled
  • The further away you get from this proportion, the more cropping/scaling that occurs
  • Images that are far-off this proportion will be anamorphically scaled and squished

Stay away from Portrait-shaped images

      • Portrait-orientation resulted in an ignored focal point

Stay away from Square images

      • The more square an image is, the more scaling (versus cropping) that happens

Stay away from traditional horizontal banner/header-shaped images

      • Horizontal banner shapes are handled inconsistently, either:
        • fills the frame based on height–which only shows a small segment of the width
        • shows the full width, which leaves the image teeny tiny, and the majority of the frame empty

Select a real focal point

    • Don’t use focal points as a way to trick the system into showing your header/banner the way you want it
    • The next visitor to the page won’t have the same size window as you
    • You may get the header to show how you want, but you’re just going to wonk-up the image everywhere else

If an image is super important, figure-out a way to get it to 16:9 proportions

      • You may have to do some Photoshop work

Stay away from images that include text

      • It’s going to get cut off somewhere, so it’s best to just not include text
      • Leverage SharePoint’s Header Text over image features instead
      • This is also a SEARCH best practice, as text in images is not searchable
