These large individual product images work great for products like shoes, but when we needed to introduce clothing items we couldn't fit the entire product in without shrinking the image down until it was too small. Owen’s solution was to have a small thumbnail preview that you could drag over to view different sections of a larger image.

Markup

So the idea is that we have a container (.image-scroller) with a fixed height and width, an image that is taller than the container (.feature-image), and a container (.preview) for the thumbnail of that image:

<div class="image-scroller">
  <img src="images/feature.jpg" alt="" class="feature-image" height="1280" width="960" />
  <div class="preview">
    <img src="images/preview.jpg" alt="" height="180" width="135" />
  </div>
</div>

Just a Dash of CSS

We really just need to assign some heights, widths, and positioning:

.image-scroller {
  height: 640px;
  -moz-user-select: none;
  overflow: hidden;
  position: relative;
  -webkit-user-select: none;
  width: 960px;
}
.image-scroller img {
  display: block;
  left: 0;
  position: absolute;
  top: 0;
}
.image-scroller .preview {
  border: 5px solid #fff;
  bottom: 20px;
  height: 180px;
  left: 20px;
  position: absolute;
  width: 135px;
}

Once the plugin is applied, there is a span with a class of indicator appended to the small preview area which represents the area you can drag up and down:

.image-scroller .preview .indicator {
  background: #000;
  cursor: move;
  display: block;
  left: 0;
  position: absolute;
  width: 135px;
}

Make it Move with JavaScript

You’ll need to start by including jQuery and my plugin on the page:

<script type="text/javascript" src="scripts/jquery.js"></script>
<script type="text/javascript" src="scripts/jquery.imageScroller.min.js"></script>

Then, you can just call the plugin on the container:

$(document).ready(function() {
  $('div.image-scroller').imageScroller();
});

Options

There are a few options that you can pass into the plugin:

  • preview: '.preview',
    Selector for the smaller preview image
  • featureImg: '.feature-image',
    Selector for the larger image
  • indicatorText: 'Drag Me'
    Text for the drag interface
