ImageReady for gimp

[Scott Durrant]

I am not an artist.  I just want to be able to turn 100k images into 10k
images.  I understand this is very easy to do with Adobe ImageReady, an
application that ships with PohotoShop 5+. 

Is there similar functionality in gimp?   Even if it's not as easy, I'm
willing to learn if there is a tutorial on optimizing the file size of an
image.
