Image quality and slight compression.
What is the difference between lossless 100% Jpeg file and a 90% (WordPress standard) and say 80% compression of the original compression?
The truth being very little difference between a Jpeg lossless image and WordPress standard 90% compression. There is also very little, ok a slight difference between Jpeg 90% and 80% compression.
Knowing this may save you extra space in your images by reducing the weight size of the images in kilobyte terms.
However, this extra step is entirely optional and not obliged. In my opinion, razor sharp images are not required for most blogs, unless of course you are running a photography or photography related blog where image sharpness is very important.
For visual reference to the differences between 100% Jpeg lossless quality to 90% jpeg and 80% Jpeg image compression from the original please visit the foto forensics website.

Good question
Image optimising reducing the file size.i.e from 640kb to 200kb (as an example)
Image resizing reducing the physical size of the image from 640 x 480 to 427 x 327 (as an example)
Thanks for asking.
So sounds like it's good to use both plugin (?), first you reduce the physical size of the image, inevitably reducing the file size...then reduce the size even more by "optimizing" I guess? Thanks again, I'll try it!
