Question

I have developed a web application using ASP.Net MVC 4, then hosted that web application on windows azure (windowsazure.com).

My website is unable to upload image/create file. Should I add some permissions?or how to add these permissions?

Please use Edit question to provide code snippet.
Give the code you’ve provided, the failing part is most probably the line:

Server.MapPath(“~/UploadImages/” + …);

What you really have to do, is first check whether that folder already exists:

string targetFolder = Server.MapPath("~/UploadImages");
if(!System.IO.Directory.Exists(taretfolder))
{
 System.IO.Directory.Create(targetFolder);
}
// then copy the file here

The “problem”, if one can say it is a problem at all, is that the server does not have this directory created when you try to put file into it. You have to first the directory before trying to copy files.
And by the way, it is not an “Azure” issue. If you take your code as is and upload it to a hoster (without manually creating or coping the UploadImages folder) you will encounter the very same issues.
