Automate the placement of one layer on another

[keepcarlson]

Hello!  I have multiple 3”x5” .jpgs.  100’s of them in fact.  For each one I need to place either a text box or another jpg in the bottom right coroner.  More or less a “watermark”, or stamp if you will, although it needs to be 100% opaque and highly visible.  I am hoping to find a way to automate placing the watermark/stamp so I don’t have to place it manually on each jpg and export.  I tried to use a macro followed by a batch job.  I brought in about 50 of the .jpgs as a layer stack, and placed the watermark at the top.  I turned layer visibility off for all but the watermark at the top.  Sadly once I started to record the macro, it would not let me record turning on the visibility of a layer.  

Can anyone advise on a workflow that might allow me to accomplish this automation?  I have Affinity Photo, Designer, and Publisher.  I do not have Photoshop (and can’t afford it).  Perhaps someone knows of an open source product that will do this?  Gimp, Inkscape?  I also tinker with python if there is a library for this type of thing?

Thank you!

I'd say give Gimp a try. I've not used it in decades, but done a quick search for tutorials on how to do what you want. They have tutorials on YouTube showing how.

Thank you so much Ron P. and Dwright!  Very much appreciate your responses.
I watched the video and tried it first and it worked perfectly!!!
Since it worked, I did not try Gimp.

Thank you again for helping me!

I watch a lot of his tutorials. Missed that one. Learned something more about AP..
