imagecreatefromjpeg() reading a dynamic image

[ThePaulius]

Hi, i've got a headache! i'm a ASP person, ive used ASPJPEG in the past, now i have to do the same thing but in PHP...

if for expamle i have an image displayed on a page as below:

<img src="<?php echo $imageDetails['imagePath']; ?>" <?php echo $imageDetails['attr'];?>/>

and i want to dynamically display that picture as a thumbnail of the original lets say, i could use this right:

<?php
header('Content-type: image/jpeg');

//$myimage = resizeImage('filename', 'newwidthmax', 'newheightmax');
$myimage = resizeImage('test.jpg', '150', '120');
print $myimage;

function resizeImage($filename, $newwidth, $newheight){
   list($width, $height) = getimagesize($filename);
   if($width > $height && $newheight < $height){
	   $newheight = $height / ($width / $newwidth);
   } else if ($width < $height && $newwidth < $width) {
	   $newwidth = $width / ($height / $newheight);    

   } else {
	   $newwidth = $width;
	   $newheight = $height;
   }
   $thumb = imagecreatetruecolor($newwidth, $newheight);
   $source = imagecreatefromjpeg($filename);
   imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
   return imagejpeg($thumb);
}
?> 

BUT!

How do I get the dynamic image to work with the script?

$myimage = resizeImage('test.jpg', '150', '120');

needs to be this kinda thing

$myimage = resizeImage('COLOR=orangered & ($imageDetails['attr']);[/COLOR]', '150', '120');

well, the image resize function is this:

resizeImage(image source, width, height);

Now, your $image[attr] array value is what, a comma seperated value? Or is it:
$image[attr][width], $image[attr][height]. It's easier if the latter is true. Then your code would be:

$myimage = resizeImage($imageDetails['imagePath'], $imageDetails['attr']['width'], $imageDetails['attr']['height']);

Otherwise, it might look something like (using a comma seperated value):

list($width, $height) = explode(',', $imageDetails['attr']);
$myimage = resizeImage($imageDetails['imagePath'], $width, $height);

Hope that helps.
