In addition to determining where an image appears on a web page, you can also set some of its display properties. These attributes include:
Text The title above the image, the caption below it, and the alt text displayed when the user mouses over the image. Alt—an abbreviation for alternate—is an image attribute designed to contain the text to display when a screen reader or text-only browser is being used to view the page.
Font attributes The color, font-family and text size used to render the image caption and title.
Alignment The position of the image relative to the adjoining text item.
Size The width and height of the image on the page. The default size is the actual size (in pixels).
Bookmark An anchor tag for the image, which you use to link to the image from another page in your website.
Link Whether or not the image is a hyperlink, and if so, the location to which it links (internal site bookmark, external web site, or an email address).
Line spacer The padding between the image and an adjoining content item.
