Automate an export with some visible layers

[mrcmrc12]

I would like to know if it is possible to automate an operation of this type: I have a PSD with various layers; I want to export a png, always leaving the three layers at the bottom visible and, from time to time, leaving one layer of the numbered ones visible.
