imagejpeg generating string not image even with header("Content-type:image/jpeg")

[cman]

does anyone know why i can't generate images with:
header("Content-type:image/jpeg");
imagejpeg($img_ number);

i've tried different examples but i always get a text output as if the
header doesn't make a difference at all.

<?php
//random_number.p hp
$img_number = imagecreate(100 ,50);
$white = imagecoloralloc ate($img_number ,255,255,255);
$black = imagecoloralloc ate($img_number ,0,0,0);
$grey_shade = imagecoloralloc ate($img_number ,204,204,204);

imagefill($img_ number,0,0,$gre y_shade);
ImageRectangle( $img_number,5,5 ,94,44,$black);
ImageRectangle( $img_number,0,0 ,99,49,$black);

header("Content-type:image/jpeg");
imagejpeg($img_ number);
?>

You're code runs fine on my server. Are you outputting some other
content before this script?

You must be testing the code using IE, which has a stupid mime-type
caching mechanism. If your script had initially produced an error
message, IE will keep seeing the contents as text.

Try testing the script again.

The standard requires a space after the colon, but the mimetype caching
issue is the better bet I think.

script to be sure

i'm actually testing the code using firefox

Re: imagejpeg generating string not image even with header(&quot;Co ntent-type:image/jpeg&quot;)

i tried with the space after the colon and it doesn't make a difference
either

while (@ob_end_clean( ));

place this before your header function

if you server has output buffering on, then it won't send the image
data correctly.

At least, that is the problem I had for my generated images...

i was hoping that would work, but sadly it didn't
i still see "ÿØÿà" in the browser

while (@ob_end_clean( ));

try adding this before the header. If your server has output buffering
on, you need this to generate image.

Hope this helps.

Are you including this file in another possibly? Or do you have
anything else in the file before this code (even a DOCTYPE)?

i'm only running the following code in a file name 'test.php':

<?php
//random_number.p hp
$img_number = imagecreate(100 ,50);
$white = imagecoloralloc ate($img_number ,255,255,255);
$black = imagecoloralloc ate($img_number ,0,0,0);
$grey_shade = imagecoloralloc ate($img_number ,204,204,204);

imagefill($img_ number,0,0,$gre y_shade);
ImageRectangle( $img_number,5,5 ,94,44,$black);
ImageRectangle( $img_number,0,0 ,99,49,$black);

header("Content-type: image/jpeg");
imagejpeg($img_ number);
?>

Did you try the

while (@ob_end_clean( ));

as the first call in your document?

OK, then, are you sure you have the correct libs compiled into PHP?

It works for me, also (on Firefox).

Live HTTP headers is showing a response of :

Also, when I view the source, the first line I get is:

Try reporting all errors to the display and see of you get a message
about something wrong.


Do you have a URL we can try?
