Images can be viewed as a slideshow or by manually clicking the thumbnails.

The gallery has support for paging which makes it possible to display large amount of images.

Images in the gallery are mentioned as a JavaScript array and every image is loaded once they are called.

Galleriffic is also SEO friendly, you can directly view any image with the specific gallery URL of it.

For the last weeks, several JavaScript image crop resources are published at WebResourcesDepot. This is because, the increase in use of such interfaces as image-based applications are on the rise & many web applications offer their users to edit their avatars besides only uploading them. So, you may need one of them : ) .

<select name="speed" id="speed">
<option value="Slower">Slower</option>
<option value="Slow">Slow</option>
<option value="Med" selected="selected">Med</option>
