Hi,

You should somephp.php?blabla return an image, including the right headers
for MIME-TYPE and such.
Should work as you described above.

The trouble will be generating a script that does that. You will have to do
some more research on imagelibs in PHP.

Good luck,

Thanks,

i did some testing with this code:

header("Contet-type: image/jpeg");
$theURL="image.jpg";
if(!($fp=fopen($theURL,"rb")))
{
print("Could not open the URL.");
exit;
}
$contents=fread($fp,1000000);


print($contents);
fclose($fp);


But must i always set the header("Contet-type: image/jpeg") before the code
begins or can i make first a musql query orso to get the rigth image and
then print the header("Contet-type: image/jpeg");?

that is content-type, no contet-type.

this is a bit odd. You have set the header to image, but your output is
plain text..
Not good.

Your html-page is asking for an image, and your script should return one.
In your case, where it cannot find the right image, try to send back an
image you know that exists containing "NOT AVAILABLE" written on it or
somethinf like that.
Do not send plain text to the browser when it expects an image.
Better write an error to some logfile.

You can do whatever you like AS LONG AS YOU DO NOT GENERATE OUTPUT.
:-)
The headers should come first.

<img src="getimage.php?fn=image1" ...>

getimage.php:
<?php

if (isset($_GET['fn']))
$image = $_GET['fn'];
else
$image = 'error';

header("Content-Type: image/jpeg\n");
header("Content-Transfer-Encoding: binary");

$fp=fopen("images/$image.jpg" , "r");
if ($fp)
fpassthru($fp);

?>

Maybe try "Content-type" and not "Contet-type" :)

another way to do it:

getimage.php:
<?php
if (isset($_GET['fn']))
{
$image = $_GET['fn'];
header("Location: images/$image.jpg");
}
else
{
header("HTTP/1.0 404 Not Found");
}
?>

Hi Jason,

That might help maybe. ;-)
