Displaying images based upon the selected values of DropDownByKey?

Hi Experts,

I need to developed an application wherein it contains DropDownByKey which contains four values and i've imported 4 images into the component. Now my question is i want to display image based upon the selected value of the dropdownkykey.

Suppose the DropDownByKey contains four values let say v1, v2, v3 & v4 and imported images are Img1, Img2, Img3 & Img4. Now if i select v1 then it shud display Img1 and v2 den Img2 so on......

Can anyone help me out to achieve this functionality.

Your help is highly appreciated
