I have created a portal theme. Every thing is coming fine along with the mast head but the requirement is changing the Mast head background picture on clicking on the refresh button. The technical term is "Image Refresh".
I have the java script which if incorporated and saved as html source code then the html page shows the reflection rightly. But I cant do it for portal.
If the source scripting for the portal can be accessed and changed then the problem has a chance to get resolved.
Thanking you in advance..
