I ran into a need for this recently, but from within a composite control in a class library. Unfortunately, the above approach fails in my context due to the relative addressing of the image to the "calling" project. I eventually got around it by using code like the following...

System.Web.UI.HtmlControls.HtmlImage visaImage = new System.Web.UI.HtmlControls.HtmlImage();
visaImage.Src = Page.ClientScript.GetWebResourceUrl(this.GetType(), pathToEmbeddedImageVisa);
visaImage.Alt = "Visa";
visaImage.Border = 0

Getting this to work with IE was another story [involving Javascript].

This is actually really quite easy:

<asp:RadioButton ID="btnBlack" runat="server" Checked="True" GroupName="ink" Text='&lt;img src=&#39;/Images/blackink.gif&#39;&gt;' />

Enjoy!
