Question

How can I add tag aroud with link to that image with JQuery?

Answer 1

This will wrap a set of images with links to them:

$('some selector for the images').each(function() {
    $(this).wrap("<a href='" + this.src + "'/>");
});

…uses .each (link), .wrap (link), and the native DOM src (link) property for image elements.

Edit Or as Pointy points out (but not pointedly), just pass a function into wrap:

$('some selector for the images').wrap(function() {
  return "<a href='" + this.src + "'/>";
});
