[RESOLVED] Using a dynamic image as an email signiture

[middleman666]

Hi all,

I have a script that builds an image on the fly, this is in a file called 'status.php', I'm trying to use this image as an email signiture.

I created a html file with the img tag in it:
<img src="http://mydomain.com/status.php?id=1" />

But when assigning this as the signiture file I just get a image not found box.

I'm guessing this is the OS security kicking in and declaring the script a threat as when I open the html file I get the 'this page is trying to run a script' prompt.

Is there any way of getting round this? Perhaps fooling the OS into thinking it's just an image?

Cheers

you can use Apache modrewrite to run your script file (renamed) as file.gif. just make sure the script outputs the right headers

[dagon]

thinking about it, it should work fine as it, as i do it myself with tracking code. but the "this page is trying to run a script'" tells me your not just returning an image file (with proper headers) on that page.

so the script has to return the headers of an image file, else it will fail.

I'm not too good at the whole modrewrite stuff so I tried another method I found on the web where you name a directory status.jpg then just place the script as the index.php file of that directory.... then you can link to mydomain.com/status.jpg
...saying that, I'm still not having any luck so here's the code I'm using:

It's just a bit of a test for now, so just ignore the output:

<?php
//Connect to Database
include('../../DB-connect.php');

//Get UserID
$id = 1;

//Get First Name
$result = mysql_query("SELECT FirstName FROM usersWHERE id = $id");
if (mysql_num_rows($result)) {
	$row = mysql_fetch_array($result);
	$FirstName = $row['FirstName'];
}

$text = 'My name is '.$FirstName;

make_wrapped_txt($text, '053871', 2, 2, 550);

function make_wrapped_txt($txt, $color = 000000, $space = 4, $font = 4, $w = 500)
{
	if (strlen($color) != 6)
		$color = 000000;
	$int = hexdec($color);
	$h = imagefontheight($font);
	$fw = imagefontwidth($font);
	$txt = explode("\n", wordwrap($txt, ($w / $fw), "\n"));
	$lines = count($txt);
	$im = imagecreate($w, (($h * $lines) + ($lines * $space)));
	$bg = imagecolorallocate($im, 255, 255, 255);
	$color = imagecolorallocate($im, 0xFF & ($int >> 0x10), 0xFF & ($int >> 0x8),
		0xFF & $int);
	$y = 0;
	foreach ($txt as $text)
	{
		$x = (($w - ($fw * strlen($text))) / 2);
		imagestring($im, $font, $x, $y, $text, $color);
		$y += ($h + $space);
	}
	header('Content-type: image/jpeg');
	die(imagejpeg($im));
}
?>

Thanks

replace your

 header('Content-type: image/jpeg');
    die(imagejpeg($im)); 

with

[code=php]header('Content-type: image/jpeg');
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0",false);
header("Pragma: no-cache");
imagejpeg($im);
imagedestroy($im);
exit();[/code]

Cheers, I've done that, but I think the problem is the Windows Live Mail client as it still didn't work.
I've just managed to add it as a signiture using hotmail.com instead and it seems to work fine.

Do you know why that might be?

Thanks for your help with this.

[dagon]

by default most email clients don't load remote images, i'm guessing live mail is set up like that.

Cheers, will keep that in mind when I use it again in the future.

Thanks for the help!
