I have made 3 posts so far.
In posts 1 & 2, I inserted a photo and made it the "featured image". That image shows up for that post in the slider perfect.y. However, in the 3rd post, when I do the exact same thing, the photo that I select for the "featured image" does not show up in the slider. Rather, it replaces the image in the HEADER. In other words, when you go the blogsite, the header image shows up as it is supposed to but the slider for this post shows no photo. Then, when you click "view post" the header changes and the header becomes the photo that was set as the "featured image".
I've consulted with my graphic artist on this who has deemed this is not user error on my part, but a flaw in the template.
I attempted to create a 4th blog entry, and the exact same problem occurred. my blogsite is blog.orginsight.com
