Upgrading Image Thumbnails… Or How to Fill a Large Display Without Your Content Team Quitting | The Signal

Preservation is usually about maintaining as much information as possible for the future but access requires us to balance factors like image quality against file size and design requirements. These decisions often require revisiting as technology improves and what previously seemed like a reasonable compromise now feels constricting.

The World Digital Library recently ran into an example of this while working on the next version of the World Digital Library website, which still has substantially the same look and feel as it did when the site launched in April of 2009. The web has changed considerably since then with a huge increase in users on mobile phones or tablets and so the new site uses responsive design techniques to adjust the display for a wide range of screen sizes. Because high-resolution displays are becoming common, this has also involved serving images at larger sizes than in the past.
