I think that if you override the Equals() method of the ImageInfo class, the CoverFlow will be able to properly select the provided item. The problem is that generally the class instances are compared by reference and when you create a new instance (new ImageInfo()...) it has different reference than the items inside the CoverFlow. If you override the Equals() method to compare the members of the ImageInfo class, the instances will be compared differently and the selection will work.
