• By default drupal provided three image styles. Thumbnail, Medium and Large
• We can add the watermark to this image styles by click edit
• There you can find override defaults. Click on it
• Now you can find select a new effect select box
• you can find overlay(watermark) option select it
• There it contains four text boxes x offset, y offset, Opacity and filename
