Caching images reduces repeated downloads on return visits, improving page load time and user experience, supporting SEO.
Hypothetical standard operating procedure
Adapt this example to your site, access, tools, and change process. It is our suggested procedure, informed by the sources below.
- Configure server or CDN to set cache-control headers with suitable expiration for images.
- Use plugins or .htaccess directives to enforce caching policies if using CMS/server that supports it.
- Test cached images behavior by visiting pages repeatedly in various browsers.
- Monitor cache HIT rates in network tab and analytics tools.
- Adjust cache duration balancing update frequency and performance.
Watch for
Lack of caching causes slower loads on repeat visits and increases server bandwidth usage.
Definition of done
Cache-control headers with long TTLs are set for image types; verified by browser dev tools caching indicators.
