Why and how php slicer borned?

First, i has been switched to linux for near 1.5 years ago. I'm familiar with it, i'm mainly a web developer and the only point that i can't get on linux is the slicing of images. Is there some tools that allows some very painly and featureless solution but i can't find any useful.

IIRC near the silvester of 2006-2007 On a week end i'll decided to create this, and after 2days of vigiling i have something buggy, unstable but working tool that nearly can do what i want.

I'm uses this with inkscape, if i have created a design in inkscape, i export that then sliceup!
(Inkscape is a very cool vector graphic drawing tool, check at: http://inkscape.org\)

Because it is mainly only for me, i only optimised for firefox, i don't want to support other browsers actually, because it's enough.
Then i decided to share this on sf.net and actually, you can download and use my code under GPL licence. Enjoy!
