Create image gallery in 4 lines of jQuery
Few days ago friend asked me to build image gallery with thumbnails for her web page. Request was pretty simple, she wanted large image and few thumbnails bellow that. Also, large image should have bar with description. When user click on thumb large image and description should change.
My idea was to use alt tag of thumb image for large image description. I already did that for jqFancyTransitions. Also, I was impatient to use jQuery’s delegate method in real life. So this is my image gallery with thumbs and description in 4 lines of jQuery.
First prepare images for gallery, large images and thumbs. We need some naming convention so let’s naming large images with suffix _large and their thumbs with suffix _thumbs. For every image we will have pair, image_xx_large.jpg and image_xx_thumb.jpg. In this example all large images will be 565×280px and thumbs will be 100×100px.
Next thing is to include jQuery in head of your document:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
After that we need layout to hold one large image and all thumbs. We need one panel with large image and description bar. Also, we need holder for thumbnails.
<div id="gallery">
<div id="panel">
<img id="largeImage" src="images/image_01_large.jpg" />
<div id="description">First image description</div>
</div>
<div id="thumbs">
<img src="images/image_01_thumb.jpg" alt="1st image description" />
<img src="images/image_02_thumb.jpg" alt="2nd image description" />
<img src="images/image_03_thumb.jpg" alt="3rd image description" />
<img src="images/image_04_thumb.jpg" alt="4th image description" />
<img src="images/image_05_thumb.jpg" alt="5th image description" />
</div>
</div>
We should add some style to our gallery:
#thumbs { padding-top: 10px; overflow: hidden; }
#thumbs img, #largeImage {
border: 1px solid gray;
padding: 4px;
background-color: white;
cursor: pointer;
}
#thumbs img {
float: left;
margin-right: 6px;
}
#description {
background: black;
color: white;
position: absolute;
bottom: 0;
padding: 10px 20px;
width: 525px;
margin: 5px;
}
#panel { position: relative; }
Now, when we have layout and CSS prepared we should add functionality to our image gallery. When user click on thumb, large image should be changed as well as description. We will replace ‘thumb’ to ‘large’ in src attribute of largeImage and use alt attribute of thumb for description. That can be achieved with following jQuery code:
$('#thumbs img').click(function(){
$('#largeImage').attr('src',$(this).attr('src').replace('thumb','large'));
$('#description').html($(this).attr('alt'));
});
And that’s it, you have fully functional image gallery for your site.
The better way for this is to use delegate method of jQuery. With delegate you’ll be able to dynamically load thumbs and use them without bind event listeners for new thumbs.
$('#thumbs').delegate('img','click', function(){
$('#largeImage').attr('src',$(this).attr('src').replace('thumb','large'));
$('#description').html($(this).attr('alt'));
});
Delegate method is added in jQuery 1.4.2. Check more about delegate().

document.getElementById(”largeImage”).src = t.src.substr(1);
}
#thumbs { padding-top: 10px; overflow: hidden; }
#thumbs img, #largeImage { border: 1px solid gray; padding: 4px; background-color: white; cursor: pointer; }
#thumbs img { float: left; margin-right: 6px; }
#panel { position: relative; }

Hi,
This is a great image gallery. I just have one question. Where do you insert all of the large images? I see the location for 1 large image and the thumbnails. I am still learning…
Thanks

I was thinking of the same thing.. I put all of the JQuery code inside the script tag.
$(’#thumbs’).delegate(’img’,'click’, function(){
$(’#largeImage’).attr(’src’,$(this).attr(’src’).replace(’thumb’,'large’));
$(’#description’).html($(this).attr(’alt’));
});
before closing the head tag. Let me know please! Thanks!

@trần công nghiệp – You don’t consider clickable thumbnails to be navigation?

Great script. I have a question about expanding the jQuery capabilities. In addition to the “description” text, I need to create a link that is dependent upon the thumb as well.
My idea was to specify two other attributes to the thumb tag “atitle” and “btitle”. I tried a title attribute but do not want the tooltip popup. The “atitle” is the name of the text link and the “btitle” is the href of the corresponding link.
I tried embedding this link into the “alt” attributes above, but this did not function properly.
Assuming the link is in the same div as the description, how would I script the jQuery to grab the “atitle” text to modify/change/replace the link text and the “btitle” text to modify/change/replace the href of that link?
Thank you.

Are the thumbnails scrollable, if I exceed the number of thumbs shown in the pic? And is there a way to make it xml compatible to load the images?
