Thumbnail script

[rbblue8]

Hey everyone..

Before i get started... I figure I should tell you that according to phpinfo(); I have

GD Support 	            enabled
GD Version 	             bundled (2.0.28 compatible)
FreeType Support 	enabled
FreeType Linkage 	with freetype
GIF Read Support 	enabled
GIF Create Support     enabled
JPG Support 	            enabled
PNG Support 	           enabled
WBMP Support 	         enabled
XBM Support 	           enabled

I'm trying to use this script

$desc=$result['descrip'];
		$date=$result['name'];
		$locked=$result['locked'];
		$pic_name=$result['pic_name'];
		$link_db=$result['db_table'];

	# Constants
	define(IMAGE_BASE, '/homepages/13/d153872232/htdocs/photos/images');
	define(MAX_WIDTH, 150);
	define(MAX_HEIGHT, 150);

	# Get image location
	$image_file = str_replace('..', '', $_SERVER['QUERY_STRING']);
	$image_path = IMAGE_BASE . "/$pic_name";

	# Load image
	$img = null;
	$ext = strtolower(end(explode('.', $image_path)));
	if ($ext == 'jpg' || $ext == 'jpeg') {	
	echo'you made it here';	
	$img = imagecreatefromjpeg($image_path);
	echo'you made it here';
	echo $img;
	} 
	if ($ext == 'png') {		
	$img = @imagecreatefrompng($image_path);
	# Only if your version of GD includes GIF support
	}
	else if ($ext == 'gif') {		
	$img = @imagecreatefrompng($image_path);
	}

	# If an image was successfully loaded, test the image for size
	if ($img) {

	# Get image size and scale ratio
	$width = imagesx($img);
	$height = imagesy($img);
	$scale = min(MAX_WIDTH/$width, MAX_HEIGHT/$height);

	# If the image is larger than the max shrink it
	if ($scale < 1) {
	$new_width = floor($scale*$width);
	$new_height = floor($scale*$height);

	# Create a new temporary image
	$tmp_img = imagecreatetruecolor($new_width, $new_height);

	# Copy and resize old image into new image
	imagecopyresampled($tmp_img, $img, 0, 0, 0, 0,
	$new_width, $new_height, $width, $height);
	imagedestroy($img);
	$img = $tmp_img;
	}
	}

	# Create error image if necessary
	if (!$img) {
	$img = imagecreate(MAX_WIDTH, MAX_HEIGHT);
	imagecolorallocate($img,0,0,0);
	$c = imagecolorallocate($img,70,70,70);
	imageline($img,0,0,MAX_WIDTH,MAX_HEIGHT,$c2);
	imageline($img,MAX_WIDTH,0,0,MAX_HEIGHT,$c2);
	echo'you made it here';
	}

	# Display the image


	echo'
		<table width="200" border="1">
		  <tr>
			<td>
			<center>
			Posted on<br />
			'.$date.'<br />
			<a href="http://photo.nightlance.com/?view='.$link_db.'">';
			header("Content-type: image/jpeg");
			imagejpeg($img);
			echo'
			</a>
			<br />
			'.$desc.'
			<br />
			</center>
			</td>
		  </tr>
		</table>
		';

and it is not going any further then.

# Load image
		$img = null;
		$ext = strtolower(end(explode('.', $image_path)));
		if ($ext == 'jpg' || $ext == 'jpeg') {	
		echo'you made it here';	
		$img = imagecreatefromjpeg($image_path);
		echo'you made it here';
		echo $img;
		} 
		if ($ext == 'png') {		
		$img = @imagecreatefrompng($image_path);
		# Only if your version of GD includes GIF support
		}
		else if ($ext == 'gif') {		
		$img = @imagecreatefrompng($image_path);
		}

it's exactly failing @ $img = imagecreatefromjpeg($image_path);

And I have no idea why...

it displays the first "you made it here" but not the 2nd.. which is how i know where it's failing.

Just the obvious first..

Is image_path correct? have you verified it actually contains the proper filename?

Yes.. That it is correct.

I gave the php script some bad code.. and when the php runtime engine threw it's error at me, it gave the absolute server path to that file. I just coyed and pasted.

:-)

I realize the path might be correct, but do you actually get a filename?

Yes. When i do a

echo $image_path;

It does provide the entire server path to the file. Including the .jpg ext.

You have a lot of @ symbols in your code. Get rid of them You do not need them if your code is properly written. At the moment it reduces the number of error messages you are getting. Probably get a better error if you don't have them. Could you please post the result of this?

I might be totally wrong, but should this code

        else if ($ext == 'gif') {        

        $img = @imagecreatefrompng($image_path);
        } 

be changed to this since it is not a pgn file?

        else if ($ext == 'gif') {        

        $img = @imagecreatefromgif($image_path);
        }

PHP Code:
else if ($ext == 'gif') {

$img = @imagecreatefrompng($image_path);
}

be changed to this since it is not a pgn file?

well-spotted. However.. the script fails in the jpg section 😃

I am a bit buffled that there is no error message, and the script just stops, even when the correct path & name are provided. Did you switch of the error reporting?
