VB.NET

' Image load from URLs is allowed
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(UrlAccessRule.Allow()) 

Pass the URLs that should be accessible in the application to allow resource loading only from them:

C#

// Image load is allowed only from the specified URL.
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(UrlAccessRule.Allow("http://mysite.dev"));

VB.NET

' Image load is allowed only from the specified URL.
