[PHP-DB] Images from database

[Randall Barber]

I have seen in several places the following line:

<img src='myScript.php' etc..etc..>

Will this tag work in both IE and Netscape?

What does myScript.php do?  Does it find an image and pass the binary data back?

Something like this--

<?php

// Code to find get a path from a database

$fp = fopen(odbc_result($qryResult, "imgPath"), "rb");
fpassthru($fp);
fclose($fp);
?>

Am I getting this, or am I missing the whole point?
Thanks
