    specific medical specialty. The topics under this section include health issues 
    of this kind. This section also explains symptoms related to different kinds of 
    illnesses and diseases. The different medical specialties are also covered in

i dont want to affect the master page just the picture should get effected ,where to add this code ?


Maybe I'm missing something, but isn't that as simple as

<asp:ImageButton Style="opacity:0.4; filter:alpha(opacity=40);" ID="ImageButton1" ... />

When you're ready to get fancier, add a rule to a CSS file and refer to it as

<asp:ImageButton CssClass="yourclassname" ID="ImageButton1" ... />

Either way, realize the effect won't appear in all browsers.
