Create array on stage, mathematically referring to objects on the stage

Ok what I want to do is create a set of small images on the stage and name them sequentially like you would an array, then refer to them mathematically in actionscript. I tried naming them as an array but it says that the name is reserved for the system or something. Does anyone know how to get an array of objects onto the stage, or have an idea of something else I could do to get the same effect?
