Adds a checkbox + download button to every thumbnail on a booru gallery. Fetches the full-resolution ORIGINAL and names the file from the post's tags. Batch select, progress, optional ZIP. Never leaves the gallery page.

.zip,
Select all, Clear, Retry failed, and the filename options.Nothing requires opening the individual post page. The gallery keeps working normally: every injected control stops event propagation, so clicking it never navigates or opens the site's lightbox.
Files are named from the post's own tags, using a template you control:
`{{tags}}`__`{{id}}` -> 1girl_solo_long_hair__1234.jpg
Tokens: {{tags}} {{id}} {{rating}} {{site}} {{user}} {{md5}} {{ext}}
Illegal filesystem characters, control characters and Windows reserved names are handled, long names are truncated on a tag boundary, and collisions inside one batch get a numeric suffix.
Three tiers, cheapest first, cached per post:
data-file-url). No extra request.dapi or post.json endpoint.og:image and the tag links. Universal, needs no API key.Bundles the selection into a .zip using a built-in store-only writer - no third-party
library is loaded at any point. Booru files are already compressed formats, so storing
costs essentially nothing.
Filename template, max tags, tag separator, parallel downloads, prefer JSON API, send
Referer, always use in-page blob download, and optional Gelbooru/Rule34 api_key / user_id.
All persisted per browser profile.
GM_download / GM_xmlhttpRequest - to save the original files.@connect * - cross-domain requests to any host. Required because every booru serves
originals from a different CDN, and the userscript managers block unlisted hosts. The
script only ever contacts the booru you are already on plus the CDN its files live on.
There is no telemetry, analytics or phone-home.GM_getValue / GM_setValue - to remember your options.Danbooru (+ betabooru), Gelbooru, Safebooru, Rule34, xbooru, tbib, realbooru, e621,
yande.re, konachan (+ .net). Adding another booru is one entry in the ADAPTERS array plus a
@match line; sites that already expose a data-file-url-style attribute work with just the
@match line.

api_key / user_id in the options; without them the script falls back to reading the post
page, which is slower but needs no key.Report problems through the Feedback tab on this script's page.
