You want to download all the GIFs from an HTTP directory. `wget http://host/dir/*.gif’ doesn’t work, since HTTP retrieval does not support globbing. In that case, use:

wget -r -l1 –no-parent -A.gif http://host/dir/

It is a bit of a kludge, but it works.

`-r -l1′ means to retrieve recursively (See section Recursive Retrieval), with maximum depth of 1.
`–no-parent’ means that references to the parent directory are ignored (See section Directory-Based Limits), and
`-A.gif’ means to download only the GIF files. `-A “*.gif”‘ would have worked too.
