- **dangling
- Show dangling images. Dangling images are a file system layer that was used in a previous build of an image and is no longer referenced by any image. They are denoted with the `<none>` tag, consume disk space and serve no active purpose.
+The `before` *filter* accepts formats: `<image-name>[:<tag>]`, `<image id>` or `<image@digest>`.
- **label**
- Filter by images labels key and/or value.
+The `dangling` *filter* shows images that are taking up disk space and serve no purpose. Dangling image is a file system layer that was used in a previous build of an image and is no longer referenced by any image. They are denoted with the `<none>` tag, consume disk space and serve no active purpose.
- **readonly
- Show only read only images or Read/Write images. The default is to show both. Read/Only images can be configured by modifying the "additionalimagestores" in the /etc/containers/storage.conf file.
+The `label` *filter* accepts two formats. One is the `label`=*key* or `label`=*key*=*value*, which shows images with the specified labels. The other format is the `label!`=*key* or `label!`=*key*=*value*, which shows images without the specified labels.
- **reference=**
- Filter by image name, specified as regular expressions.
+The `readonly` *filter* shows, as a default, both read-only and read/write images. Read-only images can be configured by modifying the `additionalimagestores` in the `/etc/containers/storage.conf` file.
+
+The `reference` *filter* accepts the pattern of an image reference `<image-name>[:<tag>]`.
+
+The `since` *filter* accepts formats: `<image-name>[:<tag>]`, `<image id>` or `<image@digest>`.
