Right, Im trying to watermark my images from the motorshow.

I have 50 pics in 1024x768 res.  I also have a 1024x768 image of the watermark with a transparent background.  All i need to do is open an image, open the watermark as a layer, merge them and resave.  Ive spent 30 mins arsing around trying to create a script that will do this for me, but Ive not got anything that works properly yet.

Can anyone give me any tips?  Im a bit of a newb when it comes to PS.

Batch processing is the way forward for this,

Try this as a guideline, alternative search for Batch Processing in Photoshop.  Its all about creating actions and batches.
