Hello again. I understand why the use of key could be confusing. It was used somewhat metaphorically in reference to the fact that I haven’t yet been able to figure out how to successfully implement FlexSlider or the Nivo Slider, so I was thinking maybe I needed to adjust the size of my images and that the image size was the “key” to unlock my understanding about what I was doing wrong or was the “key” or solution to fixing my problem. Hope that helps.
I really appreciate all your patience and help.
