HTML/DHTML/Scripting & Image gurus...

[acctman]

I think my subject covered everyone that could possibly help. I have a question, does anyone know how to scale an image maintaining the aspect ratio of the image, with or close to 350h or 350w? I don't want to change the original image at.

Is there a HTML, DHTML or Script that will force a image to be displayed with a set ratio dimension?

I want to be able to load images into a table cell and not have to resize the images manually before hand, since users will be automatically uploading images.

you can even just set the width and height in the img tag that would show it with the desired width and height if you wanna keep the ratio i don't think hahahahahahahahahaha can do that i didn't look into it but it can be done easily with a server side script.

you can just set &ltimg src="" width="350"&gt but each user will be downloading the full image = slow & more bandwidth

the following code will thumbnail the image

PHP Code:


 function resize($width, $image, $photoFolder, $thumbFolder) {
  $size = getimagesize("$photoFolder/$image");

  $length = ($size[1] * round($width / $size[0] * 100)) / 100;

  if ($length > $width) { $length = $width; $width = ($size[0] * round($length / $size[1] * 100)) / 100; }

  $source = imagecreatefromjpeg("$photoFolder/$image");
  $destination = imagecreatetruecolor($width, $length);

  imagecopyresampled($destination, $source, 0, 0, 0, 0, $width, $length, $size[0], $size[1]);
  imagejpeg($destination, "$thumbFolder/$image", 75);
 }
