The Image constructor or the IMG tag.
The JavaScript runtime engine creates an Image object corresponding to each IMG tag in your document.
It puts these objects in an array in the document.images property. You access an Image object by indexing this array.
To define an image with the IMG tag, use standard HTML syntax with the addition of JavaScript event handlers. If specify a value for the NAME attribute, you can use that name when indexing the images array.
To define an image with its constructor, use the following syntax:
new Image([width,] [height])
Image objects do not have onClick, onMouseOut, and onMouseOver event handlers. However, if you define an Area object for the image or place the IMG tag within a Link object, you can use the Area or Link object's event handlers.
The position and size of an image in a document are set when the document is displayed in the web browser and cannot be changed using JavaScript (the width and height properties are read-only for these objects). You can change which image is displayed by setting the src and lowsrc properties.
