Galleria using full size images instead of thumbnails

When I inspect the element, it indicates galleria is using full size image instead of thumbnail.

Example from Galleria documentation is http://galleria.io/docs/getting_started/quick_start/

<div class="galleria">
    <a href="/img/large1.jpg"><img src="/img/thumb1.jpg" data-title="My title" data-description="My description"></a>
    <a href="/img/large2.jpg"><img src="/img/thumb2.jpg" data-title="Another title" data-description="My <em>HTML</em> description"></a>
</div>

My code is 

<div class="galleria">
   <a href="http://upload.wikimedia.org/wikipedia/commons/thumb/2/2f/3D_Schildersdoek.JPG/812px-3D_Schildersdoek.JPG">
   <img src="http://upload.wikimedia.org/wikipedia/commons/thumb/2/2f/3D_Schildersdoek.JPG/220px-3D_Schildersdoek.JPG" alt=""/></a>

</div>

How can I make galleria use thumbnail images instead of full size images?

Solution

  • Key point is data-big attribute. Define gallery items like this.

    a href="ThumbImage.jpg" and img src="ThumbImage.jpg and data-big="LARGEIMAGE.jpg"

    <div class="galleria">
    <a href="ThumbImage.jpg">
        <img src="ThumbImage.jpg" 
            data-big="LargeImage.jpg" 
            data-title="My title" 
            data-description="My description"/>
    </a>
    <a href="ThumbImage.jpg">
        <img src="ThumbImage.jpg" 
            data-big="LargeImage.jpg" 
            data-title="My title" 
            data-description="My description"/>
    </a>
</div>

    Try updated version below.

    <!DOCTYPE html>
<html>

<head>
    <link  type="text/css"  href="galleria/themes/classic/galleria.classic.css" media="screen" rel="stylesheet"  />
    <script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
    <script src="galleria/galleria-1.3.6.min.js"></script>
</head>

            lightbox: true
            });
            Galleria.run('.galleria');
        });
