Java script shell && icon specs (width, height and colour depth)

[Koobi]

First off...
Im building a CD profile for a company and i need to build an icon so that when the CD is inserted and if autorun is enabled, the user would the icon i build as his CD drive icon.

Now im gonna use Microangelo to build the icon but im not sure what width, height and colour depth would be the best... i know for a fact that a 32bit colour depth wont be advisable coz not all users PC's support that.

The icon is actually their logo which was done in Adobe Illustrator and it has around 5 colours

Any advice would be appreciated :)
Also if you guys can give me the reason for your suggestions that would be really great :)


And...
I might want to access some exe's on the users PC....lets say for example i might want to access the users windows media executable in a certain case....I plan to use java script.....i plan to:
#create an instance of a shell object
#have the shell object call shellexecuteon my file in the CD
#And then destroy the shell object

All i want to know is if there will be a Virus alert.......i could test it out but i dont have a CD writer :(

thx
