Hello, @Anand SIngh !
Images are available and there doesn't appear to be any Azure outages in North Europe. Typically when you continue to run into this error ("The selected image is not valid for the specified location. Select a different location."), it's because of a permissions setting that is preventing you from creating images.
In the Azure portal, go to "Subscriptions". From there, select your subscription and click on "Access Control (IAM)" from the list on the left near the top. Under Check Access > My Access, click on "View my access". This will show you what role you have as well as what permissions that role has.
