The Image control displays the image specified by
the ImageUrl property. Because different mobile
devices support different image formats, you will almost always use
device-specific <Choice> elements to ensure
that each type of device receives a different
ImageUrl (which will point to a different image
format). For example, an image formatted as a

.gif file will be displayed on HTML-capable
browsers, but will not be displayed on WML-capable browsers. For
WML-capable browsers, you need an image formatted as a

.wbmp file. The Image control
itself does not provide any ability to convert images from one format
to another, or modify any image characteristics. (For example, if a
client supports only monochrome images, the Image
control will not automatically convert a color image to monochrome.)

In some cases, the ImageUrl will not contain the
URL for an image, but a scheme that indicates device-specific
information. For example, WML 1.1 phones that support glyphs
recognize the symbol: scheme. On an i-more phone,
the ImageUrl
"symbol:63726" maps to a heart
icon.
