uploading image from form --> scrambled

[Anon]

Hi,

I'm using the following code to upload an image via form and then save it. It seems to be working OK: it saves the file with the name I assign to it, and it discerns the file type etc... the prob is when the image (jpg) is saved, it gets distorted; the colors are all jacked and it's sometimes scrambled up. Does anyone know what's causing this and how to get around it?

Thanks,
Scott Zagar

	if (is_uploaded_file($_FILES['add_img']['tmp_name'])){
		$source_img = $_FILES['add_img']['tmp_name'];
		$img_size = getimagesize($source_img);
		// returns array 4 elements
		// [0] = width
		// [1] = height
		// [2] = type 1 = GIF, 2 = JPG, 3 =   PNG, 4 = SWF, 5 = PSD, 6 = BMP, 7 = TIFF(intel byte order),   8 = TIFF(motorola byte order, 9 = JPC, 10 = JP2, 11 = JPX.
		// [3] = text string with the correct  height="yyy" width="xxx" string that can be used directly in an IMG tag
		if  ($img_size[2] == 2){
			$m_filename = $m_prod->id . ".jpg";
			copy($_FILES['add_img']['tmp_name'], ".\\images\\" . $m_filename );
			$msg = "Uploaded!";
		} else {
			$msg = "Jpegs only!";
		}
	} else {
		$msg = "NOT UPLOADED..." . $_FILES['add_img']['tmp_name'];
	}
	echo $msg;

Hey Scott,
No, I don't have an answer for you...
but from what you've described and the code you posted, the problem is not in your PHP source.

The fact that this is an intermittant problem means something is messing with the works... though getimagesize() is seemingly harmless, it may be corrupting the data while it reads it. Perhaps it is that you are running getimagesize() on a temp file and are receiving an occasional byproduct of a temp file being tampered with by an outside process.

So first, I'd try running that getimagesize() funct on the file AFTER you copy it over to a standard permission file dir.
If it still desn't work, try reinstalling GD and check out your file permissions and OS settings.

Unfortunately, this one is a little too much of your own problem, except in the off-hand chance someone happens to wander by that has seen something very much like this before.
