Read the publisher’s full description
The is a simple extension to apply a 3 x 3 grid over any images found on a web page which are larger than 100px x 50px. The purpose of the grid is to help photographers visualise the Rule of Thirds. By displaying the grid over the image it is very simple to identify if a photograph's main focal points comply with the Rule of Thirds or not.
