Description:
------------
Right now I am executing shell scripts (like the one below) in order to put pictures up on my site. I would prefer to do this entirely in php code. I looked at the foreach loop and at some filesystem functions but I can't see any combination working when you don't know the filename.

sample shell script example code:

for file in *.jpg
do
    echo "<a href=\"$file\"><img src=\"$file\"/></a><br/>"
done
