Adding files into a .BIN file.

[exalos]

Adding files to already made images was something that I wanted to do too. I had posted sometime ago about this, but I never was able to do it.
I tried software like winiso and cd-mage but without luck. many people had posted but . . . noone I think was able to do it. They said just copy the files of the cd to a temporary folder ...... add the file you want and burn the cd. But this is not what me and other people want to find out.
So in conclusion, if someone knows the way ......... I , we are all ears (or eyes?).
