image manipulation

[orca0294]

I am writing a script that displays the user profile with a picture. The picture must be resized at run time to a certain size, to do so I using the following script.

// Start the session
session_start();
// The file
$filename = './profile/'.$_SESSION['photo'].'';
// Set a maximum height and width
$width = 200;
$height = 200;

// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);

$ratio_orig = $width_orig/$height_orig;

if ($width/$height > $ratio_orig) {
   $width = $height*$ratio_orig;
} else {
   $height = $width/$ratio_orig;
}

// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

// Output put in selected file

This script works soley but when implemented into any script it returns characters along these lines - -d™¤çyB\·Ìç2”UÚÕ$Ö‰µ¢išÓDoÆ 8Â:i¬Sén·ü;¾†³ê

Can anyone guide me to what would cause this? I am running php5 and the gd library is installed. I can't seem to understand why this is happening.

Thanks -

I'm assuming you are calling this script using something like <img src="getimage.php">, correct?

I don't see you set the content-type anywhere. Isn't that necessary?
ie:

http://php.net/gd

header("Content-type: image/png");

I am calling to this function with: echo imagejpeg($image_p, null, 100).
That works alone but not within a function. I do not believe content type is needed because it was originally in the script but I removed it while attempting to debug the script for this problem. Thank you for your help so far.

replying back to what you said - I can get the image to vew now but it is still leaving that long list of unknown characters.
