Acceptable Response Time:
According to Fiona Nah's study, everyone has a 2 seconds tolerance for loading time of webpages. TRUE. I'm really sick of those websites that does not show all the graphics and text properly within 2 or 3 seconds. Users may leave the website asap and switch to other websites as loading time is the most basic from of UX, and the very first interaction with a new website we encounter.
User satisfaction is achieved when experience exceeds expectations.CSS Sprites:
* Do better than your competition
* Do better than your users' expectations
Using CSS sprites, we can redue the number of image requests. By loading a big image containing all the different images in it, CSS can simply call out for different individual images within it later on .

I guess this method is also pretty simple on the designer side, we just have to simple put everything together and save on a single .png file? awesomeness!
