# This class is used to download and optimize images.

# I have not had a chance to implement me, and will not for about 3 weeks.

# If you are looking for a small project this simple API would be a good stint.

|
|
# Implement the following methods. With tests, the tests are a HUGE PITA cause
|
|
# network, disk and external dependencies are involved.

|

# as efficient as png it flips formats.
