Image button is similar in action to that of submit button, but it looks like an image. This expands designer's abilities to improve the form.
In addition to hypertext, you can use images as links. The image in this case must be place between the tags <a href=...> and </a>.
Image map allows you to assign links to different areas of the image. Used in two different versions - server and client.
You can specify the position of an image relative to the text or other images on a webpage. The alignment of images is specified by the parameter align of the img tag.
To insert an image into a document use the img tag, that has a required parameter src, which defines the address of a file with picture and alt that defines the alternative text.
To change the size of an image in HTML you can use attributes width and height of img tag.
