Kehai Image Snatcher

Daemon Image Snatcher - Professional Image Extraction Solution Advanced image extractor for Chrome developed by Kehai Systems. Deeply analyzes any webpage to identify and extract all image resources, whether visible or hidden in the DOM. COMPLETE AND AUTOMATED EXTRACTION Daemon Image Snatcher uses a modular architecture of specialized extractors to detect and capture: • Standard images: All <img> tags present in the DOM • Lazy-loading images: Automatic detection of data-src, data-lazy, data-original attributes and equivalents • CSS background images: Extraction from background-image properties, including browser-prefixed variants • Pseudo-elements: Images embedded in ::before and ::after selectors • Hidden resources: Images present in the DOM but not visible (display: none, visibility: hidden) All detected images are automatically deduplicated by URL to ensure uniqueness of extracted resources.
