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

Try this:

wget -nd -r -P /save/location -A jpeg,jpg,bmp,gif,png

Here is some more information:

-nd prevents the creation of a directory hierarchy (i.e. no directories).

-r enables recursive retrieval. See Recursive Download for more information.

-P sets the directory prefix where all files and directories are saved to.

-A sets a whitelist for retrieving only certain file types. Strings and patterns are accepted, and both can be used in a comma separated list (as seen above). See Types of Files for more information.

wget -nd -r -l 2 -A jpg,jpeg,png,gif
  • -nd: no directories (save all files to the current directory; -P directory changes the target directory)
  • -r -l 2: recursive level 2
  • -A: accepted extensions
wget -nd -H -p -A jpg,jpeg,png,gif -e robots=off{1..2}
  • -H: span hosts (wget doesn't download files from different domains or subdomains by default)
  • -p: page requisites (includes resources like images on each page)
  • -e robots=off: execute command robotos=off as if it was part of .wgetrc file. This turns off the robot exclusion which means you ignore robots.txt and the robot meta tags (you should know the implications this comes with, take care).

Example: Get all .jpg files from an exemplary directory listing:

$ wget -nd -r -l 1 -A jpg
