Hello,
I just upgraded from NOF 2013 to 2015. As instructed, I created a template from one of my sites and I opened the template in 2015. Everything seemed to be fine except my carousel of pictures. The pictures were 1/4 the size they should have been. Note that they were not resized to 1/4 of their size but they were cropped. But interestingly, only the first time through. When the carousel wrapped back to the beginning the pictures were sized correctly. I deleted the carousel and created a new one with the same result.
Screen shots the first and second time through are attached.
If you want to see the 2013 version, please go to the members tab of http://greaterpghgto.com/html/about_us.html.
Thank you.
Mike
