Richtextbox With Image

What about this on your xaml file:

<RichTextBox>
    <Paragraph>
        I want to show an image here!
        <InlineUIContainer>
            <Image Source="./image1.jpg" Height="350" Width="350" />
        </InlineUIContainer>            
    </Paragraph>
</RichTextBox>

Save the content of your RichTextBox to a xml file and retrieve as is when you need to read it.

Hope it helps.

Regards.
