Let's say I have an image URL (for example: http://theartmad.com/wp-content/uploads/2015/04/Smile-3.jpg) and I need to show it on my web page, but I do not need it's original big size, let say I need only 100px width image. Set max-width: 100px in CSS doesn't helps, because we still loading 222KB, the whole original image size, is there a possibility to show this image on my page compressed to 100px width size without server compression, only on browser? If I need to show many images, something like 20 at once, do it works quick or too slow?
Is there some staff that I can read to understand it better?
