Answer 1

Your current code sets each width and width figcaptionaccording to the first image. Try the following:

$(document).ready( function() {

    $("div[caption='true']").each(function() {
        var $this = $(this);
        var width = $("img", $this).attr("width");
        var height = $("img", $this).attr("height");
        $("figcaption", $this).css({"height":height, "width":width});
    });

});

Demo

Below is a snippet:

$(document).ready( function() {
	
	
    $("div[caption='true']").each(function() {
        var $this = $(this);
        var width = $("img", $this).attr("width");
        var height = $("img", $this).attr("height");
        $("figcaption", $this).css({"height":height, "width":width});
    });
	
});

*{margin:0;padding:0;}
.imgs{position:relative;}
figcaption{position:absolute;top:0;
    background-color:rgba(0,0,0,0.4);}
figcaption h3{text-align:center;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="imgs" caption="true">
  
   <img src="http://goo.gl/uRvjRS" width="200" height="250" alt=""/>

   </figcaption>
  
  </div>
  
  <div class="imgs" caption="true">

Try the following:

    $("div[caption='true']").each(function() {
        var $this  = $(this);
        var image  = $this.find('img')
        var width  = image.width();
        var height = image.height();

        $this.find('figcaption').width(width).height(height);
    });
});

, css:

$(document).ready( function() {
  $("img + figcaption")
    .css("width",function() { return $(this).prev().attr("width");})
    .css("height",function() { return $(this).prev().attr("height"); });
});

<img>, <figcaption> - caption = "true", - .
