Simple (& quick to learn) Jpeg manipulation

[biot023]

Hallo -- I need (rather quickly, unfortunately) to be able to write an application that compresses folders of jpegs to around 10% of their size.
Is there a simple & quick way to do this?
Like maybe someone knows of a jpegs for dummies API?
Or a really good tutorial that even I can get a grip on?
Thanks in advance for any & all assistance,
doug.

If I had a hammer...

JPEG is an already compressed format.
While you may save jpegs with zero compression, where a later compression might be of some success, I don't think you will find a possibility to compress it to 10%, as long as there aren't multiple identical files which only differ in name.

Try bzip2 with a high compression, to see what is possible.

Cheers for the reply -- I may have phrased the question badly.
What I need in essence is a class that will allow me to manipulate jpegs, or tutorials that show me how to do it, or both.
Does anyone know of anything like this?

Common sense is what tells you the world is flat.
