how about

	ls /t/*.jpg /t/*.JPG /t/*.jpeg 2>/dev/null | wc -l
or
	ls /t/*.{jpg,jpeg,JPG,JPEG} 2>/dev/null | wc -l

hmm? only one test, all done.

same here:

	ls /t/*.gif /t/*.GIF /t/*.GIFF 2>/dev/null | wc -l

or even

	ls /t/*.{gif,GIF,giff,GIFF} 2>/dev/null | wc -l

	ls /t/*.{bmp,BMP} 2>/dev/null | wc -l

how about

	for i in /t/*.{gif,jpg};
		do echo "http://host.com/images/$i"; >> /t/links ; done

get all the gif and jpg in one swoop.

DEBIAN NEWBIE TIP #12 from Will Trillich <will@serensoft.com>
:
Where is the DOCUMENTATION? It's all over the place... and there's
lots of it. Much was written for non-debian distributions, and
much was written long, long ago. But try these anyhow: on your
own system, try "man" and "info" and "apropos", and also look
under /usr/share/doc/<package>* ... Online, there's linuxdoc.org,
debianhelp.org, and debian.org/doc/ of course.  Also try
http://newbiedoc.sourceforge.net/general/index-deb-help-sys.html
and
	apt-get install dhelp
