Gallery and Metadata

Gallery and Metadata

Gallery

• Persistent - every generated image is saved to disk and available across sessions. Metadata is stored in SQLite, not by scanning directories.
• Thumbnail grid - responsive, sortable by date.
• Lightbox - click any image for full size: scroll-wheel zoom at the cursor, double-click to reset, Escape or click-outside to close.
• Image management - rename, delete, copy to clipboard, and upscale from the gallery.
• Mode labels - each image shows whether it came from txt2img, img2img, or inpainting.

In hosted/multi-user mode each user has an isolated gallery.

Metadata embedding

Generation parameters are embedded into your saved images so they can be read back later.

• PNG text chunks - standard tEXt/iTXt metadata.
• Stealth alpha - parameters can also be hidden in the least-significant bits of the PNG alpha channel, readable client-side without a server round-trip.
• JPEG XL (JXL) - images may be stored as JXL; metadata is embedded in the format-appropriate way.

Drag-and-drop remix (metadata import)

Drag or paste a previously generated PNG into MooshieUI and it reads the embedded metadata client-side and populates all your generation settings from it. It understands SwarmUI JSON (sui_image_params) and falls back to A1111-style text, with no server round-trip required.

This pairs well with image interrogation (see Prompting Guide) when you want to recover a prompt from an image that has no embedded metadata.
