How do I use Wget to download all images into a single folder, from a URL?

Wget is a powerful command-line tool used to download content from the web. If you want to download all images from a specific URL to a designated folder, follow these steps:

1. Determine the Target URL: First, specify the web page URL from which to download images.

2. Create a Folder for Storing Images: Before downloading, create a folder to store the downloaded images. For example, use mkdir images in the command line to create a folder named images.

3. Use Wget to Download Images: Wget's recursive download option helps download images from web pages. Here is a specific command example:

bash
wget -r -P /path/to/folder -A jpeg,jpg,bmp,gif,png http://example.com

Here's an explanation of each part:

• -r enables recursive download, meaning Wget starts from the specified URL and traverses all links.
• -P /path/to/folder specifies the destination path for downloaded files. Replace this with your actual folder path, such as images.
• -A jpeg,jpg,bmp,gif,png defines an accept list that restricts Wget to download only these file formats.

1. Check the Downloaded Files: After downloading, navigate to the images folder to verify the downloaded images.

For instance, if you want to download all images from http://example.com, first create a folder in the appropriate location using mkdir images, then use the above command with /path/to/folder replaced by the actual path, such as ./images, resulting in:

bash
wget -r -P ./images -A jpeg,jpg,bmp,gif,png http://example.com

This will download all supported image formats to the images folder.

The advantage of using Wget is its flexibility, support for various protocols and options, making it ideal for automated download tasks. With appropriate parameter settings, it can efficiently execute download operations.
