What is imageCloud?

ImageCloud is a jQuery plug-in that creates an image gallery inspired by the Google's Doodle design for the Christmas holidays on 2010. The doodle consisted on a group of images and frames that, when placing the mouse over then, grew to their real size displaying the whole picture. It looked like this:

Google's Doodle design for the Christmas holidays on 2010

It was interactive too: each image would be a link to the different ways in which the holidays were celebrated in different parts of the world. I found the concept really interesting (and I was not the only one), so I decided to work on it and come up with my own version. As a programming challenge.

The result is this jQuery plug-in that I started developing in late December 2010, completed in January 2011, and rebumped in 2014 after (some needed) improvements to remove bugs, clean code, and add new functionalities that make it more useful than before.

How to...

ImageCloud is super-easy to use. You only need three things:

  1. jQuery.
  2. The imageCloud plug-in.
  3. Some images to create the gallery.

Once that you have included the jQuery library and the imageCloud plug-in into your web page, place all your images into a div (other containers will work too), and add the class "imagecloud" to it. It really is that simple!

<div class="imagecloud">
	<img src="./upload/cloud1.jpg"  width="350" height="250" alt="1"  />
	<img src="./upload/cloud2.jpg"  width="200" height="300" alt="2"  />
	<img src="./upload/cloud3.jpg"  width="300" height="200" alt="3"  />
	<img src="./upload/cloud4.jpg"  width="200" height="300" alt="4"  />
	<img src="./upload/cloud5.jpg"  width="250" height="175" alt="5"  />
	<img src="./upload/cloud6.jpg"  width="250" height="200" alt="6"  />
	<img src="./upload/cloud7.jpg"  width="300" height="225" alt="7"  />
	<img src="./upload/cloud8.jpg"  width="300" height="200" alt="8"  />
	<img src="./upload/cloud9.jpg"  width="300" height="200" alt="9"  />
	<img src="./upload/cloud10.jpg" width="300" height="225" alt="10" />
	<img src="./upload/cloud11.jpg" width="300" height="225" alt="11" />
	<img src="./upload/cloud12.jpg" width="250" height="150" alt="12" />
</div>
Important: Notice how all the images have the width and height attributes defined. Webkit powered browsers (ie: Chrome and Safari) need those attributes set for imageCloud to work properly.

The result looks like this (mouse over the pictures to see the animation):

1 2 3 4 5 6 7 8 9 10 11 12

You can open the example above on a new window by clicking here. Reload the page and see how the pictures are placed in different locations every time the page loads, also the pictures will have different sizes and each time a different part will be displayed.

But that's just the basic display. The imageCloud plug-in is highly customizable, and provides de user with many different parameters to get the desired effect:

Parameter Type Default Value Description
width Numeric 600 It sets the width of the area where the image will be displayed. It is defined in pixels. Default value: 600.
height Numeric 400 It sets the height of the area where the image will be displayed. It is defined in pixels. Default value: 400.
color Color Type #cc0000 This is the border color for the images. Examples of correct values: "#ff00ff", "#ccc", "rgb(128,128,0)", etc. Default value: "#cc0000".
link Boolean false If sets to true, then the images will link to the page indicated in the title attribute. Default value: false.
speed Numeric 200 It indicated the speed of the effect in milliseconds; a lower value means a faster effect. Default value: 200.
borderSize Numeric 6 It is the size of the box border in pixels. Default value: 6.
borderStyle Border-style Type solid Defines the border style that the generated boxes will have. It is a border-style type (solid|dotted|dashed|inset|...). Default value: "solid".
borderRadius Numeric 0 Makes the frame border rounded (similar to border-radius, it doesn't work in older versions of IE). Default value: 0.
boxWidth Numeric -1 If a positive number is provided, all the images will have the same specified width. Default value: -1.
boxHeight Numeric -1 If a positive number is provided, all the images will have the same specified height. Default value: -1.
random Numeric true If set to true, the boxes will start displaying from a random location in the frame; If set to false, the pictures will start displaying from the top-left corner. Default value: true.

If you set the "imagecloud" class to the box that contains the images, all the default values will be applied. If you want to modify them, you'll have to make a JavaScript call to the imageCloud function and specify the values that you want to change:

<script type="text/javascript">
	$(document).ready(function() {
		$("#myImageCloud").imageCloud({
			width: 500,
			height: 500,
			color: '#aabb44',
			link: true,
			speed: 150,
			borderSize: 3,
			borderStyle: "groove",
			borderRadius: 3
		});
	});
</script>

<div id="myImageCloud">
	<img src="..." width="..." height="..." title="http://www.alvaromontoro.com" />
	<img src="..." width="..." height="..." title="http://www.improvedin.com" />
	...
</div>

You can visit this demo page that will allow you to check how changing the different values would affect the animation.

You may have noticed already that not only the pictures are displayed at random positions, with random sizes, but also the part of the picture that is shown changes every time that the page is loaded. This may be inconvenient in some cases as the displayed area may not be of interest.

Wouldn't it be great to be able to choose the size of the picture and the part that would be displayed? You can do that too! Apart from the parameters listed above, there are four attributes that can be set in the images and that turn imageCloud into an even more porwerful tool:

For example, imagine that we have this picture of a woman riding a horse, and we want to make sure that we display it with the same size and the same area every single time. For that we need to identify the size of the area to be shown (width and height), and the top corner of it within the picture (posx and posy):

Example of the data- values needed

So if we add the attributes data-width="93" data-height="115" data-posx="98" data-posy="38" to the image, the generated picture will always be the same. And what better way to see than with an example? Here you can see it working:

1 2 3 4 5 6 7 8 9 10 11 12

You can open this web page to see the demo above on a new window. Notice that although the position of the images changes, the size and the area that is displayed for each of them remain always the same.

Download

You can download the latest version of imageQuery by clicking on this link. The zip file includes the source code (12K), minified version of the plug-in (5K), and some demo pages that show it working.

Also, don't forget to visit the imageCloud GitHub repository for past (and future) releases, and for new features.
