Position watermark 20px from bottom and bottom left automatically

Question

I am automating the application of watermarks in photoshop using a batch process. Is there anyway I can position the watermark always 20px from bottom and bottom left regardless of the size of the image the watermark is being placed on?

Currently the watermark is appearing relative to the center (after moving it manually) but because the images are different sizes it never appears bottom right

This can definitely be done through a script - you need to look at the doco for the artLayer.Translate method in the Javascript Ref Guide in your Photoshop installation directory. I'm not sure if you can do it without scripting.

Use it like this after you've figured out the deltas you need for any given document:

var lyr = app.activeDocument.activeLayer;
lyr.translate("-50px","-50px");
