They say that a photo worth a thousand words, but at the same time, one photo occupies same size as of thousands words. In the early stages of the web, we only used to see pages with static contents, i.e. some images, few paragraphs of text and that was all at that time. But nowadays, we have interactive and dynamic contents, javascript applets, ajaxified apps, database driven sites, server side scripting and many more things which not only on one hand enhances user experience but on the other hand also, slows down the loading of web pages.
In this fast paced information era, we all want to access things in less time. For example you have to download a file and it is available on two web sites. One is static web site with only your desired content and the other one is fully loaded with things you may like. Of course, the second one will be much likely to be accessed by you in the future but at that moment, you will want to go to the static page, because of less loading time. So we can conclude that the loading time of web pages plays a significant role in web designing process. Follow these simple steps to compress images right now!

For testing purposes, I uploaded some wallpapers from my hard disk. They are 54 in total and collectively occupied 18.7 MB. After smushing, I got the exact same quality with the size loss of nearly 22% {4266 KB}. By Googling, you can find various method which will tell you how to optimize loading time of web pages, but the service I have mentioned performs image optimization automatically for you and all you have to do is to point the path of images and you will get compressed images with no loss in quality! The service was launched 3 days ago and has served thousands of visitors in this short period. The developers will be doing some updates in the site later on so stay tuned with their blog. I am sure it will help you a lot whether you want to optimize images for your web site, or want to send images via email attachment. The FireFox add-on is also available to smush pictures right from the browser.
