@Jeny Francis-Oracle Can you please post a solution which can be applied by other users who have the same question?

Where does the href need to be prefixed to what object or text/column/etc? To the link/image text inside the dashbaoard page? Are you doing this inside an analysis?

Please share the knowledge. The community is only as good as the information shared and so far the "solution" only makes sense to you since you're sitting in front of it. We can't see your screen :)
