About
Sometimes, you just need a way to randomly display images from your filesystem.
Simply point this tool at one or more directories, and then open the specified port (default 8080) in your browser.
A new image will be selected if you open / directly, or if you click on any displayed image.
Browser history is preserved, so you can always go back to any previously displayed image.
Supported file types and extensions are jp[e]g, png, gif, and webp.
Builds available here.
Filtering
You can provide a comma-delimited string of patterns to match via the include= query parameter, assuming the -f|--filter flag is enabled.
Only filenames matching one or more of the patterns will be served.
You can also provide a comma-delimited string of patterns to exclude, via the exclude= query parameter.
Filenames matching any of these patterns will not be served.
You can also combine these two parameters, with exclusions take priority over inclusions.
Both filtering parameters ignore the file extension and full path; they only compare against the bare filename.
Sorting
You can specify a sorting pattern via the sort= query parameter, assuming the -s|--sort flag is enabled.
A value of sort=asc means files will be served in ascending order (lowest-numbered to highest).
If a file exists with a numbered suffix one higher than the currently displayed file, it will be served next.
A value of sort=desc means files will be serve in descending order (highest-numbered to lowest).
If a file exists with a numbered suffix one lower than the currently displayed file, it will be served next.
In either case, if no sequential file is found, a new random one will be chosen.
For sort=asc, the lowest-numbered file matching a given name will be served first.
For sort=desc, the highest-numbered file will be served instead.
If any other (or no) value is provided, the selected file will be random.
Note: These patterns require sequentially-numbered files matching the following pattern: filename###.extension.
