wget [option]... [URL]...
Non-interactive download of files from the Web, supports HTTP, HTTPS, and FTP protocols, as well as retrieval through HTTP proxies.
Works in the background, allows running from cron.
Can follow links in HTML pages and create local versions of remote web sites, fully recreating the directory structure of the original site, referred to as recursive downloading.
Designed for robustness over slow or unstable network connections; if a download fails due to a network problem,
it will keep retrying until the whole file has been retrieved.
If the server supports regetting, it will instruct the server to continue the download from where it left off.

Use this option when mirroring sites that require that you be logged in to access their content. The login process typically works by the web server issuing an HTTP cookie upon receiving and verifying your credentials. The cookie is then resent by the browser when accessing that part of the site, and so sets your identity.
Mirroring such a site requires Wget to send the same cookies your
browser sends when communicating with the site. This is achieved

-r -l1 means to retrieve recursively, with maximum depth of 1. --no-parent means that references to the parent directory are ignored, and -A.gif means to download only the GIF files. -A "*.gif" would have worked too.
