Be aware that this has legal implications. Don't put anything on a web site you would not be willing to publish. Sudden changes in style are jarring and unpleasant for the reader.

Images make a big difference in loading time.
Rather, make the image smaller by reducing the actual size. This will save time in loading. Warning statements can also be offered if a link will lead to very large document or image. Having lots of small images can also cause a loading problem, since the WWW browser has to ask the server for them one at a time. Consider these issues about images as you create the page.
