Select next image in folder to replace smart object in batch recording.

Hi,

How can I tell my batch recording to choose the next image in a specific folder to replace the smart object?

I'm recording batch action to replace smart object, but the recording just stops at the first selection in the image folder, I want it to automatically go for the next picture to replace the smart object.

After placing and updated the image, I want it to automatically export with a different name too, how can I do this ?

I'm using CS6.

Please tell me how
