Use case 2: Retrieve pre-existing cookies from your web browser
Code:
gallery-dl --cookies-from-browser browser "url"
Motivation:
This use case is useful for users who want to download images from sites that require login credentials. By retrieving pre-existing cookies from the user’s web browser, ‘gallery-dl’ can authenticate the user and access content that would otherwise be restricted.
Explanation:
The ‘–cookies-from-browser’ flag in the ‘gallery-dl’ command is used to specify that the command should retrieve cookies from the user’s web browser. The ‘browser’ argument is used to indicate the specific browser from which the cookies should be retrieved (e.g., Chrome, Firefox).

Example output:
Upon running the ‘gallery-dl’ command with the ‘–cookies-from-browser’ flag and the URL, the command will retrieve the necessary cookies from the user’s web browser. These cookies will then be utilized to authenticate the user and access and download the restricted images from the specified URL.

Motivation:
This use case allows users to obtain the direct URL of an image from a site that supports authentication with a username and password. This can be useful for users who want to directly link or share the image rather than downloading the entire gallery or collection.
Explanation:
In this use case, the ‘gallery-dl’ command is used with the ‘–get-urls’ flag to indicate that the user wants to retrieve the direct URL of an image. The ‘–username’ and ‘–password’ flags are used to specify the authentication credentials required by the site. By providing the URL along with the command, ‘gallery-dl’ can access the site and retrieve the direct URL of the image.
Example output:
By running the ‘gallery-dl’ command with the ‘–get-urls’, ‘–username’, ‘–password’, and URL arguments, the command will authenticate the user using the provided credentials. It will then retrieve the direct URL of the image from the specified URL and display it as the output.
Use case 4: Filter manga chapters by chapter number and language
Code:
gallery-dl --chapter-filter "10 <= chapter < 20" --option "lang=language_code" "url"
Motivation:
This use case is ideal for users who want to filter manga chapters based on specific criteria such as chapter number and language. By using the ‘–chapter-filter’ and ‘–option’ flags, users can easily narrow down their search and download only the desired manga chapters.
Explanation:
The ‘–chapter-filter’ flag in the ‘gallery-dl’ command allows users to specify a filter for the manga chapters based on certain criteria. In this use case, the filter is set to retrieve only chapters with numbers greater than or equal to 10 and less than 20. The ‘–option’ flag is used to further refine the filter by specifying the language of the desired chapters using the ’lang’ attribute.

The output will display the chapters that meet the specified criteria, allowing the user to download only the desired chapters.
