All i am looking to do is add a sequentially numbered watermark to a set of images for easy referencing within a large gallery, so for example the first image says "1/1500" in the bottom right hand corner. The second image says "2/1500" and so on.
I would happy to just have 1, 2, 3, 4... It doesn't need the 'of 1500' if that is adding complexity.
This seems so simple you would think it was a basic function in either Lightroom or Photoshop but i can't see that it's possible without some complex script.
You can do this using the LR Slideshow module and then use 'Export JPEG Slideshow' to create individual sequentially numbered files. How are these to be posted or viewed (ref. gallery).
