Question

I really don’t know what’s wrong here and why it isn’t recreating the new image to a new directory. Please help! The image isn’t being created for some reason. I’m coding everything in Microsoft’s WebMatrix.

    public static function imgResize($imgdir){
        list($width, $height) = getimagesize($imgdir);

        $ratio = $width/$height;
        $new_height = 90;
        $new_width = round($new_height * $ratio);

        $new_image = imagecreatetruecolor($new_width, $new_height);
        $old_image = imagecreatefromjpeg($imgdir);
        imagecopyresampled($new_image, $old_image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

        imagejpeg($new_image, "gal/newimages/", 100);
    }

Answer 1

imagejpeg needs a filename, not a directory. Try:

imagejpeg($new_image, "gal/newimages/" . basename($imgdir), 100);

also, does the folder exist? If not, you need to create it first.
