You'll be using opendir and readdir to get the contents of a directory, and
is_dir to check whether to follow down a directory structure. As you loop
through the contents of a directory, test the filename to see if it meets
your definition of image (ie .gif extension or whatever), display the
image, or store it's filename in an array, or whatever, and use break to
drop out of the loop currently reading that directory's contents.

There have been a number of snippets of code published here recently for
tracking through directories and reading the contents, so a skim of the
archives may be rewarding.
