Latest Update : Version 2.0c:
Changed a couple things here and there and added some options.
There is now a mode displayed in the console so people know what options are being used.
There are now two quality options (highspeed/highquality) highspeed is used by defualt.
There is now a way to specify the number of threads to use. Specifying 0 will behave the same way as not specifying one at all.
A usage message is added for people who run the application normally.

Usage: Drag images or folders containing images on the executable.
If you would like to benchmark add "-bench" without quotes to the file name.
If you would like to use high quality mode add "-q" without quotes to the file name.
If you would like to specify number of threads to use add "-thread=" followed by the number of threads you want to use (no spaces, without quotes) to the end of the file name.
You can use multiple modes at the same time.
Because most of this was from an old application and uses most of .Net built in stuff I will provide the source:
