Nis 2012 placed icons on images in windows picture library, how do you remove them?

I am using nis 2012, Windows 7 Home Premium 64 bit . After installing nis, the view of my picture library changed from

thumbnail images to icons (a sunflower with blue and green background - ugly and useless to me). Files are OK but nearly all picture images are covered with icons.  I need to see the photo image and can not get the library to revert back to original display mode.

Already tried   organize/folder&search options/view/ and unchecked..... show icons, display file icon on thumbnails

Still showing icons....... I need help!

Thanks
