Ultra Galleries

A userscript that adds a full-screen gallery, resizing tools, and batch ZIP downloads to kemono.su, coomer.su, nekohouse.su, pawchive.st and their mirrors (kemono.cr, coomer.cr, coomer.st, pawchive.pw).

Originally based on Better Kemono Galleries, since rewritten. It uses only native browser APIs: no jQuery, no SweetAlert2, no UI libraries.

Installation

Install a userscript manager: Tampermonkey or Violentmonkey.
Install the script from Sleazy Fork, or directly from GitHub.
Open a post on any supported site.

Your script manager checks for updates automatically.

Features

Gallery

Original resolution: Loads full-size images. Originals load only near the viewport and are freed when you scroll away, so memory stays flat on very large posts. Toggle Auto-load Original Images in Settings → General.
Immersive viewer: Thumbnail strip with drag-to-scroll, hover previews and a right-click menu (open, download, copy URL, remove from gallery).
Thumbnail strip modes: Floating layers the strip above the image and hides it with the controls, so fullscreen is truly fullscreen. Docked pins it to the bottom.
Zoom and pan: Mouse wheel, toolbar buttons, double-click / double-tap, drag with inertia, and touch pinch.
Slideshow: Adjustable delay, pause on hover. Waits for a playing video to finish.
Fullscreen: Native browser fullscreen, in-page (CSS) expansion, or ask each time. Toggle with f.
Resize buttons: HEIGHT (fit height), WIDTH (fit width) and FULL (original size), for the whole post or per image.
Sort order: Site order or natural filename sort (A→Z / Z→A), so page_10 comes after page_9. Useful for comic posts.

Video and attachments

Video: Plays inside the gallery with native controls, and is included in batch downloads. Original filenames are kept.
Attachments: .clip, .psd, .zip, .pdf and any other downloadable file is collected, shown with a file-type placeholder, and downloadable from the gallery.

Downloads

Individual download: One click per image, video or file.
Batch buttons:
- DL ALL: one ZIP with every item in the post.
- DL IMAGES: a ZIP of images only, in reading order (…-images.zip).
- DL FILES: a ZIP of videos and attachments only (…-files.zip).
Streaming ZIP: Files are zipped with fflate in STORE mode as they download. On Chromium browsers the ZIP streams straight to a file you choose, so large posts use little memory. There is no ZIP64: archives are capped just under 4 GiB, and larger ones stop with a clear error.
Date preservation: Each ZIP entry carries the post's published date, so 7-Zip, WinRAR, Explorer and Keka restore the original modification time.
Custom naming: Patterns for ZIP and image names using {title}, {artistName}, {fileName}, {index}, {date_published}, {date_edited}, {date_imported} and {date}.
Cancel: Stops queued and retrying requests immediately. Navigating to another post does not abort a running download.

Performance and reliability

Persistent cache: Fetched images are stored in IndexedDB with LRU eviction. Downloads reuse images already in memory, then the cache, before using the network.
Request deduplication: Concurrent requests for the same URL share one fetch.
Pawchive rate limits: Requests to Pawchive hosts go through a 1 request/second pacer with a custom User-Agent. This includes video. Signed temporary links (?e=…&s=…) keep their signature.
SPA and HTMX safe: Uses the Navigation API with history fallbacks and survives hx-boost page swaps. Pawchive's head cleanup does not remove the injected styles.
Safe fetching: Media is only requested from the supported sites. Links in post text that point elsewhere are ignored.
Mobile and accessibility: Touch gestures, focus-trapped dialogs, ARIA announcements, :focus-visible rings and prefers-reduced-motion support.

Usage

On a post you will see a button bar with GALLERY, HEIGHT, WIDTH, FULL, DL ALL, DL IMAGES, DL FILES and ⚙️ Settings. Open the gallery with the button or the g key. Click a thumbnail to view it.

Keyboard shortcuts

Key	Action
`g`	Open / close the gallery
`k` / `←`	Previous image
`l` / `→`	Next image
`Home`	First image
`End`	Last image
`Space`	Start / pause slideshow
`+` / `=`	Zoom in
`-`	Zoom out
`0`	Reset zoom and pan
`f`	Toggle fullscreen
`?`	Show help
`Escape`	Exit fullscreen, or close gallery

g, k and l can be rebound in Settings → Keyboard. The rest are fixed. Shortcuts are disabled while typing in an input.

Settings

Tab	Contents
General	Animations, thumbnail strip and mode, notifications, fullscreen, image loading
Gallery Viewer	Navigation arrows, zoom and pan, slideshow
Downloads	Date preservation, persistent cache, file naming
Sorting	Media order
Post Actions	Show or hide the top action-bar buttons
Thumbnails	Show or hide the per-image buttons
Button Labels	Custom text for every button
Keyboard	Rebind shortcuts
Advanced	Export, import, or reset settings (JSON)

Troubleshooting

No styles after an update: Force-refresh the page once so your script manager re-fetches the stylesheet.
Save dialog appears before a ZIP: Expected on Chromium. The ZIP streams directly to the file you pick.

Changelog

4.5.2

Pawchive signed temporary links keep their ?e=&s= query. Stripping it caused 403 errors.
Clicking a post image opens the gallery even though the site now binds its own click-to-expand.
Restyled UI: amber accent on graphite, no glows, blur or hover lifts, sentence-case labels, lighter font weights.

4.5.1

Only fetches media from supported sites.
Navigating to another post no longer aborts a running ZIP. Cancel is immediate. Large files download one at a time. Archives over 4 GiB stop with an error instead of being written corrupt. Dismissing Save As no longer triggers a second download. Out-of-range post dates no longer break ZIP creation.
"Remove from Gallery" is no longer undone by lazy loading. Arrow keys and Space work after clicking a thumbnail or button. The slideshow waits for videos.
#anchor links no longer reload the post UI. "Auto-load Original Images" applies immediately.

4.5.0

Lazy original loading near the viewport, freed when scrolled away.
Downloads reuse in-memory and cached images before using the network.
Turning animations off no longer affects the host site.
Fixes: skipped images stop downloading, pinch-zoom state sync, settings focus.

4.3.x

Post Actions and Thumbnails hide toggles are scoped separately, and now apply correctly on first render.
Settings split into focused tabs with descriptions and dividers.
Date fallback no longer stamps ZIP entries with the download time.

4.2.x

ZIP entries carry the post's published date.
Attachment support (.clip, .psd, .zip, .pdf, …).
DL ALL split into DL ALL, DL IMAGES and DL FILES with distinct archive names.

Native fullscreen (Native / CSS / Ask) and the f shortcut.
Request deduplication, hardened Pawchive pacer, per-navigation request cancellation.

4.0.1
