In order to select image elements with a png extension in jQuery, you can use attribute selectors.

For your question, you want to match any img element with a src attribute that ends with ($=) .png, so your solution would be $("img[src$='.png']"). If you want to mark those items with a specific class (say, png), you would do: $("img[src$='.png']").addClass('png');

You can use the same style to select elements with any attribute you desire. For instance, to find all anchors with a hash value for the href attribute, you can use: $("a[href^='#']")

jQuery has a big list of different types of selectors, which you can read about here: http://api.jquery.com/category/selectors/
