This looks like a great example to add to weberdev. 
would you care to spend 3 minutes and let other PHP developers enjoy from 
your knowledge?

You are one click away from doing a good deed :)

You can save them and then call them up, but then you have to use a cron or
something to empty out the folder.  Here's how I save it:

//Image created and everything up here, this is the very end of it
$myTime = time();
ImagePNG($im, "../spool/jp$myTime.png"); //this creates a unique name
chmod("../spool/jp$myTime.png", 0666); //leading 0, then the code for the
mode you want

print "<img src='../spool/jp$myTime.png' border=0 width=\"520\"
GALLERYIMG=\"NO\" height=\"500\"></td>";

I hope this helps!

Im trying to use dynamic buttons, and Im trying to figure out how to get 
around the header call.
I figure use output buffering, but so far Ive only come up with errors.
Anyone see a better way or any errors in my code. Thanks

nb:  Uncomment the echo() statement to get the error.

//echo 'Hey<br>';

function button($word) {
    header("Content-Type: image/png");
    $im = ImageCreate(100, 50);

    $black = ImageColorAllocate($im, 0, 0, 0);
    $white = ImageColorAllocate($im, 255, 255, 255);

    $start_x = 50 - (strlen($word) * ImageFontWidth(5) / 2);
    $start_y = 25 - ImageFontHeight(5) / 2;

    ImageString($im, 5, $start_x, $start_y, $word, $white);


button('Hello World');
