1) Place all the images which you want to use in the shapes folder
My Documents\Tableau Repository\Tableau Version\Shapes\[Create New Folder]\
2) Create a worksheet and add Shapes as per your design using images you placed in tableau repository folder --> In tooltip mention "Click to go Goto Operations"
3) Place that worksheet in your Dashboard
4) Create a URL action and mention URL
when you hover on the Sheet you will get the "Click to go Goto Operations" tooltip and when you will click it will redirected to url
Hope this helps

Thanks for your reply but I had mentioned in my post that I already knew this and wanted to know whether it could be done on image URL.
Thanks for the reply but unfortunately this dosen't help me.
Looks like I might need to change the URL Name and use redirection to actual URL. Something of that sorts ..
