How to solve this Iframe Src Problem

  

i created the Iframe in Expression and set src as parameter.I have the folder in application path there we have Images.And also the Path was stored in DB.
In DB we saved like Test\Image.jpg. this "Test" folder was in Application path.During Running we get the url from DB the set to Iframe src.
Test folder exist in "C:\Program Files\OutSystems\Platform Server\running\TestWebSites\"

some times it works when the URL in DB like ( ..\Test\Image1.jpg) and another time it works for (Test\Image1.jpg)
