I think you should set the compression/quality as a variable (maybe even one passed to the constructor) as 60% is not going to be acceptable to most designers. For a static value I'd reccommend 85% or even 90

I also have a thumbnailing class being distributed from most of the class distro sites and from here.

Also note: rather than the mime_content_tyep and imagesx / imagesy calls, you could use getimagesize - the first index return is width, second is height and third is imagetype

so

Code: Select all

$f_type = getimagesize($base_image);
$this->c_image = ($f_type[2] < 4)
                        ? ($f_type[2] < 3)
                            ? ($f_type[2] < 2)
                                ? ($f_type[2] < 1) ?
                                NULL
                            : imagecreatefromgif($base_image)
                        : imagecreatefromjpeg($base_image)
                    : imagecreatefrompng($base_image)
                    : NULL;
if($this->c_image !== NULL)
    {
    // $f_type[0] is width
    // $f_type[1] is height
