Adobe Fireworks is a bitmap and vector graphics editor aimed at web designers.
For questions strictly about photoshop scripting! Photoshop is a raster graphics editor by Adobe Systems, that is industry standard for creating, modifying and treating images and graphics
I find fireworks has an easier time dealing with vectors because they re first class objects while in photoshop they re actually a combination of a vector mask and a colour fill
How to create vector graphics and then generate icons from them?
I have fireworks 8 as well as photoshop cs3 on my windows pc but i m more familiar with fireworks
