Need to increase or decrease your Wordpress Jpg compression?

For some reason Wordpress does not seem to give you an option to increase or decrease the JPG compression ratio in the media settings. This means your scaled images are stuck at the default compression ratio. The default is 90%. This is quite high and on high resolution, high quality images, this is not going to be noticable. If you are finding your images are too slow to load, 60% is a good balance of quality verse speed, but it will be a noticable quality difference.
