little help with GD

[ajdegans]

Hey there ive got this code, and it works nice but theres one thing: it saves a resized image... i dont want that, i want them resized on the fly and the original image kept intact at all cost!

heres the code:

function gallery($randomphoto3[picture]) {
	$randomphoto="SELECT * FROM photos ORDER BY RAND() LIMIT 1";
	$randomphoto2=mysql_query($randomphoto) or die("Could not get a random photo");
	$randomphoto3=mysql_fetch_array($randomphoto2);

// The file 
$filename = $_SERVER['DOCUMENT_ROOT']."/images/gallery/$randomphoto3[picture]"; 

// Set a maximum height and width 
//$width = 125; 
//$height = 125; 

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

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

if ($width && ($width_orig < $height_orig)) { 
	$width = ($height / $height_orig) * $width_orig; 
} else { 
	$height = ($width / $width_orig) * $height_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 
imagejpeg($image_p, $filename, 100); 

return $randomphoto3[picture];
}

How should i modify this code to work the way i want? i thought on editing this part:

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

but i have no clue how 🙁

The line to look at is [man]imagejpeg[/man], but wouldn't it be an idea to store the original and the resized version?

maybe it is a better idea yes, but how do i do that 🙁

im a total newb on GD and most functions and combinations of functions are not making any sense to me or im not really knowing how to use them ( yes i looked on php.net ) 🙂

Um, how do you save two files? Virtually any image gallery program does this.

[ajdegans]

but im writing the socalled gallery program myself 🙂

Anyway, im little tired of thinking about GD.... Im going to look into it later. Or if you got some script and want to send me some snippet blinkblink i would be extremely happy 😃

Yes (I ADMIT) im a bit lazy :evilgrin:

So all you're wanting to do is save the modified image under a different name from that of the original file, then!

imagejpeg($image_p, $filename.'_thumb.jpeg', 100);

Or any other convention that takes your fancy (for a start, strip the .jpg off the filename before taking on the _thumb bit). Nothing to do with GD LIb per se.
