Follow the steps listed below to protect your copyright in a batch:

  1. Specify the Location folder to which watermarked images will be exported (copied).
  2. Specify Image Size if required. Leave this option unchanged to use the original size.
  3. Select an appropriate image quality. Let’s use Maximum.
  4. Select the Add watermark option and type the text.
  5. And you are done. Click Export to run the batch watermarking.

Picasa Limitations

  • In Picasa, image watermarks are not supported. Only text can be used.
  • You cannot specify font settings (font name, size, color, etc). In Picasa, a watermark is white text (for dark photos) and black text (for light photos).
  • You are not allowed to specify the location at which a watermark should be embedded. In Picasa, a watermark is added to the lower-right corner of photos.
