Seeking Pic/image merge (w/text or small img) batch application

I don't know if what I have in mind exists or not. I am hoping the following description is enough to determine - is this possible and if it currently exists in any related application.

Essentially, what I need to do is place/position a couple/several lines of text in a region (upper left, upper right, lower left, somewhere I can mark or tag) of a picture/image. Likely a TIFF, could also be a PDF or perhaps almost any other format.

The text would differ (has to be unique) per pic/image file.

The real need is if if this could be automated in a batch sequence.

It would likely help the cause to point out that the bulk of one category (format) of the pic/image file is always the same size/resolution and a TIFF. it can be said the same for another category, such as JPG and/or PDF.

Any thoughts on this? Basically, where I work, this is done by hand editing one image at a time to type in the text and position then save it back. But for hundreds of drawings/documents it is still time consuming, tedious and expensive to produce.

I am open to suggestions. Thanks for any constructive response.

Thank you very much for your reply.

I do know that Gimp, Paint.net, Photoshop and others do not seem to have quite this feature I am looking for (as I have those applications myself).

So far, my online search seems to have born some fruit, but I am not sure until I actually get the time to experiment with what I found.

Maybe this, maybe not:
