Nothing happens because you're not doing anything with the result. See the documentation for imagecopyresampled:

imagecopyresampled() will take a rectangular area from src_image [...] and place it in a rectangular area of dst_image.

After running this function, the result will be in $dst_r, which is still an in-memory image resource. You now have to save it to a file. This can be done with the imagejpeg function, for example:

imagejpeg($dst_r, "$dirname/avatar_cropped.jpeg");
