Load up the image in your web browser by copying and pasting the URL link to the banner image into your web browser�s address bar to see if the image loads.

Yes, it's possible. When obtaining the Adsense HTML code (from Google's control panel) which you place inside your templates/pages there is an option where you specify criteria which reads: 'Alternate ad URL or color'
For the 'Alternate ad URL or color' you specify a URL to an HTML file. You need to create this HTML file and upload it somewhere to your web site. Inside the HTML file you can place the banner rotation code that you can obtain from the PowerSeek Banner Manager.
