The SiteRepository contains two string properties that access site icons: siteIcon and Favicon. These properties contain a path to an uploaded image file.

Set a default value for the image properties that point to image directories that are the start path for all images.

For example, create an image directory such as /images/storefront/site// that can store all images for a site. For each new site, you would only have to fill out the filename part of the path, such as /images/storefront/site//facicon.ico or /images/storefront/site//
siteIcon.png.
