I'm looking for a simple yet effective software to watermark a lot of photos in batch.
I have to apply a transparent png watermark image on 400 photos.
The program have to place the watermark at a custom position relative to the bottom right corner of every picture.
I would have done this in photoshop, but the scriptable action doesn't allow me to do conditionnal placing if the photo is portrait or landscape.
I'm looking for a free lightweight program.
