"Photogallery rendered here." but no gallery

I am trying to add a Gallery page. I followed the steps in the FAQ by setting up a gallery called “Gallery”, adding two sample photos, creating a page with the marketing URL /Gallery, and then adding the gallery component by selecting “Photogallery:Gallery” from the dropdown. So it appears vin65 is aware that I’ve created a gallery and lets me add it. But when I view the page, it simply says “Photogallery rendered here.” in text on the page, and I don’t see the images. Do I need to turn something else on to make this work? I looked in Web Site Settings and “Photo Galleries” is checked.
