I noticed that there's no option for width and height dimensions to be in inches or centimeters, only pixels. Photoshop CS2 has this already so i know it can be done.
Perhaps in your next release you will add inches and centimeter support?
That's true. The physical dimensions are important for printing and not so important if the pictures are only used on web.
I'll have to think about this a bit more not to make the image creation page too complicated for new users.
Next version might have better printing support, so maybe this will be addressed as well.
