RSS Image Widget

RSS Image Widget fetches images from any RSS/Atom feed that uses enclosures and displays them in a responsive grid with a built-in lightbox. Works as both a classic widget and a Gutenberg block.

Features:

• Widget + Block — Use in sidebars (classic widget) or anywhere in the block editor
• Lightweight — No jQuery, no external CDN. Just a tiny vanilla JS lightbox (~2 KB)
• Responsive grid — CSS Grid layout adapts to any container width
• Lazy loading — Images use native browser lazy loading
• Accessible — Lightbox supports keyboard navigation (Escape to close)
• Zero configuration — Just add a feed URL and go

Upgrading from v2.x:

The Bootstrap classes (row, col-xs-12) and external Lightbox2 CDN have been replaced with clean semantic HTML, a responsive CSS Grid layout, and a bundled vanilla JS lightbox. If you had custom CSS targeting the old classes, you will need to update it to use the new .rss-image-gallery BEM classes.
