Check the concept "icon based navigation filters". Basically you can have 2 images say one for android and one for iphone. When user clicks android, all reports will be filtered for android
No that's not working for me
Not sure exactly what you're asking. Can you clarify?
You will have to create a worksheet with the image and then add that worksheet to your dashboard, you can then use dashboard actions to navigate.
To answer your question (if I am getting you correctly) is; no, you cannot add actions to an image directly on the dashboard.
Let me know if this helps.
