Image Moo - Image manipulation library

[quote author="Mat-Moo" date="1365539999"]1) My testing shows that the ratio all remains and works correct, although there have been several updates since my last post

2) The library is designed to resize images, you simple save them to another folder and them serve them instead. The library can't do that as not everyone wants that... about 10 lines of code your end to implement it! Serving images dynamically the way you are will kill your server if the traffic gets too high.

3) New version available 1.1.5

Also almost finished the EE plugin for this [/quote]

What is the difference between these two?

get_data_stream($filename="")

save_dynamic($filename="")
