The BBC has a server-side image service which provides developers with multiple sized versions of any image they request. It works in a similar fashion to http://placehold.it/ but it also handles the image ratios returned (where as placehold.it doesn't).

The original BBC News process (and my re-working of the script) follows roughly these steps...

  • We set the width & height HTML attributes of the image to the required size
  • We know what size the image needs to be because each div has custom data-attr set server-side to the size of the image
  • We then set a class of image-replace onto each newly created transparent image
• We use a 250ms setTimeout to unblock the UI thread and which calls a function resizeImages which enhances the image-replace images so their source is now set to a URL whe
