|
|
|
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.
|

|
|
|
|
2022-10-18 21:58:15 +00:00
|
|
|
A new image will be selected if you open `/` directly, or if you click on any displayed image.
|
2022-09-16 19:52:59 +00:00
|
|
|
|
|
|
|
|
Browser history is preserved, so you can always go back to any previously displayed image.
|
|
|
|

## Filtering
|
|
|
|
|
|
2022-10-20 01:37:12 +00:00
|
|
|
You can provide a comma-delimited string of patterns to match via the `include=` query parameter, assuming the `-f|--filter` flag is enabled.
|
2022-10-20 00:56:42 +00:00
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
2022-10-20 01:42:08 +00:00
|
|
|
You can also combine these two parameters, with exclusions take priority over inclusions.
|
2022-10-20 00:56:42 +00:00
|
|
|
|
|
|
|
|
Both filtering parameters ignore the file extension and full path; they only compare against the bare filename.
|
|
|
|
|
|
|
|
|
|
## Sorting
|
|
|
|
|
|
2022-10-20 01:37:12 +00:00
|
|
|
You can specify a sorting pattern via the `sort=` query parameter, assuming the `-s|--sort` flag is enabled.
|
2022-10-20 00:56:42 +00:00
|
|
|
|
2022-10-20 01:42:08 +00:00
|
|
|
A value of `sort=asc` means files will be served in ascending order (lowest-numbered to highest).
|
2022-10-20 00:56:42 +00:00
|
|
|
|
|
|
|
|
If a file exists with a numbered suffix one higher than the currently displayed file, it will be served next.
|
|
|
|
|
|
2022-10-20 01:42:08 +00:00
|
|
|
A value of `sort=desc` means files will be serve in descending order (highest-numbered to lowest).
|
2022-10-20 00:56:42 +00:00
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
2022-10-20 01:42:08 +00:00
|
|
|
For `sort=asc`, the lowest-numbered file matching a given name will be served first.
|
2022-10-20 00:56:42 +00:00
|
|
|
|
2022-10-20 01:42:08 +00:00
|
|
|
For `sort=desc`, the highest-numbered file will be served instead.
|
2022-10-20 00:56:42 +00:00
|
|
|
|
2022-10-20 01:42:08 +00:00
|
|
|
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`.
