Displaying Employee Photo on the Approval Page

I tried displaying it on Workflow page but the way to display it is downloading the photo on application server and setting that in the property of Image item programatically.So what i did is i added a button on the workflow page and when user clicks on this button then system will display the photo on a diiferent page.
Following steps need to done to achieve the same:-
1) Add a new item on the page

2) Set the properies as shown below:-

3) To open the photo in different page set the Target Frame as _blank 

4) In destination URL put OA.jsp?page=/oracle/apps/xxekk/approval/webui/xxEmpPhotoPG&akRegionApplicationId=800

5) Put the logic in controller file to fetch photo from database and display it on the page.
