Batch toggle layers and export

Hi There!   I think Templater for Adobe After Effects can help you accomplish what you are looking to do — you would need either the Pro or Bot edition of the extension. 

In general, you setup a Google Sheet where each column header matches the name of the layer you want to change.  Each row in the sheet is a new output, so every cell under a column header is what the layer will "receive" when Templater reads the Sheet data and injects it into the layer.  Templater can batch render a single composition that is re-versioned and then rendered for each row in a sheet.

For hiding and showing layers, you can use Templater's flags which are terms wrapped in double braces.  For example, you can specify {{off}} as one of the values for a cell and the corresponding layer will "turn off" in the composition when Templater processes that value.

You can learn more about the extension here:  https;//dataclay.com/templater

You can learn more about how to control layer visibility through spread sheet data by watching this segment of this video.

Hopefully this can help with your workflow tasks!

Not really a workflow one would employ. One would rather simply duplicate the parent comp 100 times and add a single image to each of the duplicates and add them to the render queue. For such tasks there are plenty of scripts on AEScripts.com, though you may not necessarily find one that covers your exact scenario and you may need to combine multiple scripts or individual functions.
