Making things smaller

With images there are many things you can do to get a high quality image but get a really small file size. If you want to use images on the web you will have to have a small file size so the images load quickly enough so users don’t have to wait for it to load. But you also want to keep the same quality; you can do many different things to do this by using the .PNG file type and using optimisation methods on this website. But if you’re using an image to use on screen so say your presenting it to some peers or something, you’d still have to think about file size as you’d need to get all the images onto the CD, this is if you have lots of images to show.
