String-Library-Bitmap-Class?

I am working on this for two weeks but I couldn’t success :hitman2:

Trying to do this:

name0 = Image's Class Name
name1 = My bitmap instance name

addBitmap(name0:String,name1:String);

I need a function like that… But I don’t know how to call class in the library with using String argument? [COLOR=Silver]Sorry for my poor english…[/COLOR]

Thanks…
