Description
public replacePlaceholderImage (string $variable, string $src[, array $options])

This method allows to replace a placeholder image that may be fully formatted in Word (border, shadows, effects...) by an image of our choice.

If one does not set the width, height and/or dpi options the method will use the corresponding data taken from the original placeholder image.
