Windows fully supports localization, scale, and accessibility for web images and packaged text and images. Web servers can take advantage of these features by returning specific images depending on the variables encapsulated in a query string. Packaged images and text use the Resource Management System and require no further changes than what your application already does for localization, scale, and accessibility.
For web images, add the optional boolean attribute addImageQuery to the image, binding, or visual node to have Windows automatically append query strings. The query strings are appended to the image URL provided in the notification payload when the image is requested from the image service. The image service used should respond with the appropriate image based on the parameters supplied in the query string.
