Spectra

A variation on the masonry grid image gallery with the row alighment constraint removed. Oh, it also has an admin interface so you can set it up and forget it.

• Color Analysis: Automatically extracts color palettes from images to create cohesive galleries
• Smart Thumbnails: Generates and caches responsive thumbnails in multiple sizes
• EXIF Preservation: Maintains all photo metadata through processing
• Ownership Verification: Embeds steganographic proofs in images
• Live Configuration: Hot-reload config changes without restarts
