A PHP-based solution that automatically detects a visitor's screen size and delivers appropriately re-scaled, cached versions of a site's HTML images without requiring any markup changes. It works via an .htaccess rewrite, a small JavaScript snippet that stores screen size in a cookie, and a PHP script that resizes and caches images on the fly.

Use cases

• serve smaller images to mobile devices without changing img tags
• reduce bandwidth costs for image-heavy responsive websites
• add responsive image support to an existing site with minimal setup
• automatically cache resized image variants per breakpoint
• support retina displays with appropriately sized images
• speed up page loads on slow, low-bandwidth mobile connections

When to choose

• you have an existing PHP site (Apache or nginx) and cannot modify image markup
• you want a quick, drop-in responsive images solution with minutes of setup
• your CMS cannot generate multiple image resolutions itself
• you want automatic caching of downscaled image versions per screen size

When to avoid

• your stack is not PHP (e.g. Node, Python, static site generators)
• you can use modern native solutions like srcset, picture element, or a CDN image service
• you need WebP/AVIF support or advanced image optimization
• you are starting a new project - modern responsive image standards are preferable
