Sell, since there is a resizing, there a JPEG compression, and you loose in quality, it is normal. What you can do is change the jpeg_quality setting to have a better quality.Reply

As I said, you are loosing quality because it resizes and recompresses the image. I am not sure we can do anything about it.Reply
