custom placement of signature on individual photos in a batch

You may be able to do what you want to do without needing user intervention using a Photshop sample action I created as a model.  The action uses a couple of what I call run twice scripts to pull it off.  You use these run twice in the beginning and the end of actions,   These scripts perform a save and restore function for the action.    The action begins by using these script which see its being run for the first time because its footprint is not in the documents meta-data and in this first run it will place its footprint into the meta-data along with some Photshop state information and perhaps manipulate the document.  The action ends by running these scripts a second time the see their footprint and save state information in the meta-data which it removes, perhaps do some manipulation and restores the documents state it recorded in the first run.

The Sample Action save the documents resolution with the script then changes the document size to a known size without resampling the document. All the dose is scale the documents print width to a known size by changing its resolution not a single pixel is changed.  Once you have scaled a document to a known width its easy to add  correctly seized watermark layers in the location you want using tools  like adding a text signatures layer,  Placing colored custom logo or using a custom shape layer. The sample action adds all three.  Once it done adding  the watermark layers the action runs the script a second time to restore the document to its original resolution. My Package download
