The image element includes images from an external source.

The supported file formats are JPEG, PNG, other SVG and GIF (without animation).

The 'href' attribute specifies the adress of the source image.

The image tag has x and y as attributes for positioning.

Also has a width and a height, that usually don't match those of the source picture.

In this case the attribute 'preserveAspectRatio' controls how the image is scaled.

On iOS this feature is not supported. In the following example you should see a picture of a butterfly.
