Hi all,

Need you help in creating a custom validation class for Umbraco properties.

The class will get a Node ID, check if it's valid and return a string to the image.

Something like:

        public static string GetImageLink (int link) {

            if (link != null && link > 0 )           {

               var imageLink = umbraco.Media(link).umbracoFile; }

       }

Questions:

1. Where should this class be created? it's a MVC project

2. What libraries should I add (and how) so commands like umbraco.Media / uQuery.GetNode / Node.GetProperty will work?

Thanks.
