I have several files, I want to make them optimized images for PageSpeed Insights. How to do this with PHP using gd or imagemagick?
When you upload an image process it with the function bellow. This process cleans meta information from images and stop Google for being annoying.
$im = imagecreatefromjpeg($target_file);
