Render Automation

I am doing some simple top-down renders for use in photoshop.

 I need to take an object, randomize the noise modifier, zoom to the selection and save the rendering in a folder like.... 1.bmp, then randomized again, zoom, and save as 2.bmp etc....

I need to do only nine renders per object, but I have to so like 100+ objects so this script would be invaluable.....

I can use maxscript to record everything but the saving the image...

Any help is greatly appreciated!
