jQuery addClass to all img

jQuery addClass to all img

Hi.

I'm having some issue on FAQ page. The basic FAQ is the dropdown image doesn't have any class or id.
We want when user click the question it toggle open and i'm using jQuery to add some class on the image.
But the issue is it add the class on all the image question, not only current toggle question.

How can i achieve this? Can someone guide me.
Here is the script that i'm working for.

  1. {source}
    <script type="text/javascript">
        jQuery(document).ready(function(){
        jQuery("a").click(function(){
            jQuery("img").addClass("rotate");
        });
    });
    </script>

                            If the temperature is adjusted at 27 degrees Celcius or less in the process of oil extraction, you can sing a cold press. Although it is easier to press oil when heated, the flavor and aroma of the oil will be impaired. Olive oil oiled with cold press is laborious and produces rich flavor instead of less yield.

                            This Apple vinengar is an organic product, it does not sterilize the vinegar itself, it does not contain sulfur dioxide (In the filling process line the steam sterilization of the bottle is done). This is to make the most of the efficacy and benefits of acetic acid bacteria becomes active, vinegar fermentation progresses, the color may become darker. However, the quality of the product will not change as the activity of acetic acid bacteria becomes active. Although sometimes suspended sediments may be seen, this is also derived from acetic acid bacteria, which does not affect quality.
