Kathy, from your contributions list, it looks to me like you did upload it. It is image no. 70 on the 52 Photos page, so you have to go to the page, view all the images, and page forward to the seventh page of images. Then click on the image and you will see an "add/edit" button to its right. Click on that, then on the left side of the new page, click on "Remove from image." Then save your changes.
