Hello @SueBonnarArt I'm sorry you're having trouble with this. It may depend on if the image is used in a "background" or just a separate image.
There is some basic info about managing/adding photos used as a background in this article: https://squareup.com/help/us/en/article/6887-adding-pictures-to-your-square-online-store
If your image was just added into your site and not as a background, try this: Select the section with the image, then select the image to see image options appear in the editing panel.
Do you know if this is photo that you had previously added, or is this a placeholder image that was included in your template?
