What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
An archived JavaScript experiment from Filament Group for delivering mobile-first responsive images that scale to larger sizes based on screen width, using an .htaccess rewrite trick and a ?full= query parameter. The project is no longer maintained and recommends using Picturefill or native responsive image features instead.
Use cases
- serve smaller images to mobile devices and larger ones to desktops
- avoid downloading both image sizes in responsive layouts
- implement mobile-first responsive images without UA sniffing
- study historical responsive image techniques
When to choose
- you need to maintain a legacy site already using this technique
- you are researching the history of responsive image solutions
When to avoid
- starting any new project - it is archived and unmaintained
- modern browsers - use native srcset/sizes or the picture element
- you need support or updates
