Turn any folder with photos & videos into a web gallery.

  • thumbnails & multiple resolutions for fast previews
  • mobile friendly website with customisable themes
  • only rebuilds changed files: it's fast!
  • uses relative paths so you can deploy the pages anywhere
  • works great with Amazon S3 for static hosting

Quick start

Simply point thumbsup to a folder with photos & videos. All nested folders become separate albums.

npm install -g thumbsup
thumbsup --input ./photos --output ./gallery

Screen recording

There are many command line arguments to customise the output. See the website for the full documentation:

Sample gallery

Thumbsup requires the following dependencies:

And optionally:

  • FFmpeg to process videos: brew install ffmpeg
  • Gifsicle to process animated GIFs: brew install gifsicle
  • dcraw to process RAW photos: brew install dcraw
  • ImageMagick for HEIC support (needs to be compiled with --with-heic)

You can run thumbsup as a Docker container (thumbsupgallery/thumbsup) which pre-packages all the dependencies above. Read the thumbsup on Docker documentation for more detail.

docker run -v `pwd`:/work thumbsupgallery/thumbsup [...]

If you want to contribute some code, please check out the contributing guidelines for an overview of the design and a run-through of the different automated/manual tests.


While a lot of effort is put into testing Thumbsup (over 400 automated tests), the software is provided as-is under the MIT license. The authors cannot be held responsible for any unintended behaviours.

We recommend running Thumbsup with the least appropriate privilege, such as giving read-only access to the source images. The Docker setup detailed in the documentation follows this advice.
