I tried to post a new picture on it. It's a photo of one of my items, Apology Plate. It's in JPEG format, after being downsized it's just under 200 KB. I am going through the steps, choose file, upload image, add tagline, so far so good. And the new picture will show, along with the new tagline. However, it won't stay. If I leave and then come back, my new picture is gone (but the new tagline stays put).
What am I missing?
