Image Crop

I am trying to create a script that will crop an image to 200x200 but I keep getting the error:
The image “[location/to/page]” cannot be displayed because it contains errors.
Here's my code:

Code: Select all

$orig = 'photos/1c23e596271d8eabb2e58d65c79b4beb.jpg';
list($width,$height) = getimagesize($orig);
    $imageResized = imagecreatetruecolor(200, 200);
    $imageTmp     = imagecreatefromjpeg ($orig);
    imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0, 200, 200, $width, $height);

    imagejpeg($imageResized,100);   
Thanks.

1. Are you sure the source image file exists?

2. An appropriate Content-Type header should be sent before sending image data.

Code: Select all

header('Content-Type: image/jpeg');
3. Do you want to create a file named "100", or do you want 100% quality?

Code: Select all

imagejpeg($imageResized, null, 100); // ($image, $filename, $quality)

I think you probably want to do this:

Code: Select all

imagejpeg($imageResized,null,100);

Yes, it does exist.
I have the appropriate header. It's the first thing, right before the DOCTYPE declaration.
I changed it to

Code: Select all

imagejpeg($imageResized,null,100); 
and I'm getting the same error.

That could be the problem. Image files do not contain HTML. Image data and HTML are not sent in the same server response.
