Unfortunately, I did not. I too was able to put in a static image but wanted a different feature image for each page. I wrote to the folks who designed the template and the only advice was to reinstall the theme. Had already done that to make sure it wasn’t something I had done on my end. They want you to pay for the right to read their forum. I work for a university and so that isn’t possible for me.
Best of luck in figuring it out.
