The problem with that function is that it is going to dither things down
to 8-bit colour for you and the resulting thumbnail isn't going to look
very good. Sometimes for thumbnails that is not an issue though.
imagecopyresampled() does a very nice job of scaling images without losing
quality, but you need GD2 to use it.
