Here I demonstrate the use of inline images in the midst of text. Here is a small image <img src='small.jpg' /> embedded in a sentence. Now we have a slightly larger image that is automatically put in its own block <img src='medium.jpg' /> and finally we have a large image which is automatically placed on a page by itself and prevented from being autoscaled when the user changes from S to M to L. Try changing sizes and see how the different embedding styles behave. <img src='large.jpg' /> Here I demonstrate the use of inline images in the midst of text.
