Step 1: Prepare your markup

Let's suppose you're using a <form> with hidden <input> elements to record the ordering of the images in your collections. (For a description of how to use this <form> approach, see Talking to the Server Using The afterMove Event.) A simple example of this could be:

...

<form action="#" id="reorder-images-form">
    <a href="myImage1.jpg" class="flc-imageReorderer-item">
        <img src="myImage1.jpg" alt="image 1 thumbnail" />
        <span>Image 1</span>
        <input name="image 1" value="0" type="hidden" /> 
    </a>
    <a href="myImage2.jpg" class="flc-imageReorderer-item">
        <img src="myImage2.jpg" alt="image 2 thumbnail" />
        <span>Image 2</span>
        <input name="image 2" value="1" type="hidden" /> 
    </a>
    <a href="myImage3.jpg" class="flc-imageReorderer-item">
        <img src="myImage3.jpg" alt="image 3 thumbnail" />
        <span>Image 3</span>
        <input name="image 3" value="2" type="hidden" /> 
    </a>
    ...
</form>

...

<form action="#" id="reorder-images-form">
    <a href="myImage1.jpg" class="flc-imageReorderer-item">
        <img src="myImage1.jpg" alt="image 1 thumbnail" />
        <span class="flc-reorderer-imageTitle">Image 1</span>
        <input name="image 1" value="0" type="hidden" /> 
    </a>
    <a href="myImage2.jpg" class="flc-imageReorderer-item">
        <img src="myImage2.jpg" alt="image 2 thumbnail" />
        <span class="flc-reorderer-imageTitle">Image 2</span>
        <input name="image 2" value="1" type="hidden" /> 
    </a>
    <a href="myImage3.jpg" class="flc-imageReorderer-item">
        <img src="myImage3.jpg" alt="image 3 thumbnail" />
        <span class="flc-reorderer-imageTitle">Image 3</span>
        <input name="image 3" value="2" type="hidden" /> 
    </a>
    ...
</form>

...

Step 2: Write the script

To make the HTML you just created do something special, you'll need to create a file to contain your initialization script - the script you write to apply the Reorderer to your image collection.

jQuery(document).ready(function () {
    return fluid.reorderImages("#reorder-images-form");
});

jQuery(document).ready(function () {
    var opts = {
        selectors: {
            movables: "[id^=pic-movable]"
        }
    };
    return fluid.reorderImages("#reorder-images-form", opts);
});

...

Step 3: Add the script to your HTML

You'll need to add your initialization script, along with the Infusion library, to you HTML file. In the header of the file, link to the Javascript files with <script> tags:

...

That's it! That's all you need to do to make your images reorderable!

...

Step 4: Apply styles

You can style your image gallery any way you choose (of course), or use the default Infusion Image Reorderer style.

Using the default styles

You can take advantage of the Image Reorderer styles provided with the component by simply adding the default styling class names to your markup. The Image Reorderer will take care of the rest.

...

The fl-reorderer-horizontalLayout will lay the images out horizontally, and will make sure that the drop marker shows up between the thumbnails properly.

Customizing the styles

If you choose to use CSS classname different than the defaults, you can override the defaults using the options parameter to the reorderImages() function.
