Compress jpeg on server with PHP

Question

I have a site with about 1500 JPEG images, and I want to compress them all. Going through the directories is not a problem, but I cannot seem to find a function that compres

Answer 1

The solution provided by vlzvl works well. However, using this solution, you can also overwrite an image by changing the order of the code.

    $image = imagecreatefromjpeg("image.jpg");  
    unlink("image.jpg");
   imagejpeg($image,"image.jpg",50);

This allows you to compress a pre-existing image and store it in the same location with the same filename.
