Thumbsup generates HTML galleries for existing photos and videos.
What it does
- Thumbsup groups photos into albums, based on criteria you define (e.g. per folder).
- It creates HTML pages for every album.
- It generates thumbnails & multiple resolutions for internet-friendly browsing.
- It only rebuilds thumbnails if the source files have changed: it’s fast!
- It generates a fully self-contained website, which can be copied onto a USB stick or deployed on a static web server.
What it doesn’t do
- Thumbsup never changes your input folder. In fact, it doesn’t need write access at all.
- It’s not a full application / web server, and doesn’t have “server side” logic.
- It doesn’t have the concept of users, logging-in, etc.
Albums are a central concept in Thumbsup. Albums are a virtual collection of photos and videos, regardless of where the files are on disk. When generating the gallery you can specify how albums are created, e.g.
- 1 album per folder and sub-folder
- 1 album per date, e.g.
A file can belong to zero, one or many albums.
Thumbsup uses a few tricks to generate galleries as quickly as possible:
- it caches all metadata into a local database (
thumbsup.db) to avoid re-parsing the input files every time
- when reading metadata, it runs several
exiftoolinstances in batch mode to process up to 300 photos/sec
- it check file modification dates to only build thumbnails when necessary
- it runs thumbnail generation in parallel to make use of all CPUs
Standing on the shoulder…
There is no need to re-invent the wheel when dealing with photo and video-processing.
Thumbsup uses well known tools under the hood, like
These tools each have more than 13 years of development and troubleshooting, and provide all the capabilities we need.
Fun fact: ImageMagick will soon be 30 years old!
