I'm trying to write a pure-bash random image script. (thttpd is working perfectly, i'm not installing perl/php and apache for one script) I've got the actual random-numbering working fine (in a seperate script), I can get the value it returns, but how do I make the main script take that number and return a filename depending on which one it is? I'm thinking that I should do something like: 
if [ $? = 1 ]; then return "1.png"; fi
but I can't return a non-numerical value. How do I return a filename?

BTW, don't tell me to just install Apache and PHP, i don't have space (225mb /) nor do I need all that for something as low-demand as my server. Sure, the script will select a random avatar, but PHP would be overdoing it if I was to install it just for one simple script.

    OK, I'll try that.

    This is what I have so far:

    avatar.png: 
    #!/bin/sh

./random.sh | ./pic.sh

    random.sh: 
    #!/bin/sh

cd pics
set *
shift $(($RANDOM % $#))
echo "$logos/$1"

    and pic.sh: 
    #!/bin/sh

echo "Content-type: image/png"
cat pics$1

    Should I send the content type before random.sh and pic.sh? Also, since I copied those in, I've since modified pic.sh.

    After much Googling, I came up with this: 
    #!/bin/sh

echo Content-type: image/png
cd pics
set *
shift $((RANDOM % $#))
cat < "$1"
    It works fine from the command line, but Firefox says that it contains errors.
