script output actual image data

[Anon]

I want to be able to do this in a html file for a banner program...

<a href="redirect.php"><img src="printimg.php"></a>

The browser will call printimg.php and the script will respond with raw binary data--printing out an image... and then if it's clicked, well that's not related...

Note this has nothing to do with something like this:

<?php

print("<img src=\"someFunctionThatReturnsTheFilenameOfAnImage()\">");

?>

So how do I output an image? Doesn't that involve setting the appropriate headers, etc?

HI there you are on the right track with this header idea.

You add this into a file and call via your html code in the src of the image: "pic.php?id=1"

--- SNIP ---

$query = "SELECT image FROM tblpic WHERE id=$id";

$result = mysql_query($query);
$image=mysql_fetch_array($result);

Header("Content-type: image/gif");
echo $image[pic];

--- SNAP ---

thats it
