With JQuery comes the lightbox plugin, which helps to overlay the image in a webpage with the larger image. While working on the images in a webpage, it is normal to show the thumbnail of the images. These thumbnails are guided into the javascript code using the lightbox plugin. The actual images are stored in the images folder and the CSS folder holds the Javascript file where the lightbox class will be called. The thumbnail inserted into the html page will be linked to the images folder in the .CSS file. It makes web designing very simple because the lightbox plugin automatically edits the javascript code.
