If you drag an image item from the dashboard pane onto the dashboard and then right click on the image you can "set URL" which when the image is clicked upon the page will appear (so add your project page URL in that box)
Hey Thank you Steve, that really helped....
But one thing, can we embed username and password also? so that there is no need to insert the credentials again and again...
Sorry, I assumed that the dashboard containing the logo/images used for navigation was already published to the same server as the projects you're navigating to (in which case the user would log in to view the initial dashboard and any subsequent URLs fired from that dashboard wouldn't require another log in because they're on the same server).
Can you describe where the dashboard you want to navigate from is hosted and where the project folders you want to navigate to are located?
