<h4><span id="propertyvalue">Property Value</span>
</h4>

<p><b>String</b>
</p>

<p>The image displayed by this <b>ImageBrush</b>.</p>

<p>This property is read/write. The default value is null.</p>
<span id="remarkssection"></span>
<h4><span id="remarkssection">Remarks</span>
</h4>

<p>The <b>ImageSource</b> property can be used to reference images
in the JPEG and PNG file formats.</p>

<p>The string provided for the <b>ImageSource</b> property is
interpreted as a Uniform Resource Identifier (URI). This is in
contrast to an Internationalized Resource Identifiers (IRI). This
distinction means that characters used to identify an
<b>ImageSource</b> that are outside of US-ASCII will need to be
encoded.</p>

<p>Relative references are permitted. The starting location for the
relative reference is the HTML page that contains the current
Silverlight plugin.</p>

<p>Cross-domain or protocol-qualified URIs are also permitted.</p>

<p>If you are not accessing cross-domain sources, you should
consider using <a href="m_imagebrush_setsource.htm">SetSource</a>
rather than setting <b>ImageSource</b> directly. This provides the
advantage of being able to track the download. Also, you can
download as a package and access parts from within the package.</p>

<p>In JavaScript, you can set the value to null or empty string at
runtime to cause the image to unload and no longer render. Doing so
does not fire an <a href=
"e_imagebrush_imagefailed.htm">ImageFailed</a> event. In contrast,
setting an <b>ImageSource</b> to a URI value that does not resolve
will fire an <a href="e_imagebrush_imagefailed.htm">ImageFailed</a>
event. Also, a <a href=
"m_dependencyobject_setvalue.htm">SetValue</a> error is thrown,
even if <a href="e_imagebrush_imagefailed.htm">ImageFailed</a> is
handled.</p>

<p>You can specify an initial XAML value of "" (empty string) and
then set the value in script at a later time, to create a
nonrendering placeholder.</p>

<p>The <a href="e_imagebrush_imagefailed.htm">ImageFailed</a> event
can occur if the initial <b>ImageSource</b> attribute value in XAML
does not specify a valid source.</p>
