You can create card images for specific locales and a default image for all locales. The images need to be placed in an image set that allows the browser to display the image associated with the requested locale. If the browser requests a locale for which you have not defined an image, the All Locales image is displayed. If an All Locales image is not available, the browser displays the Image not Available card.
To add an image to the set, perform the following steps:
On the Home page, Identity Servers > IDP Global Settings > Authentication Card Images.
Click the card image.
Click Plus icon and specify the following details:
File: Click Choose File, then browse to the location of the file.
Locale: Select the locale from the list.
Click Add.
