Question

i have a link

<a id="DownloadLink" href='controller/action' target="_blank">Download File</a>

that has to open a image in another tab or page. but it offers me to download the file.

my action looks like this

public FileContentResult GetSurveyFile(int Id)
        {
            if (Id == 0)
                return null;
            Survey survey = Repository.GetItem(Id);
            if (survey.File == null)
                return null;

            return File(survey.File.FileContent.ToArray(), survey.File.ContentType,survey.File.Name);
        }

where the content type is an image/jpeg

whats wrong?

How a browser handles image files is up to the browser/OS/user preferences. To absolutely guarantee that it is opened and not downloaded, simply wrap the image in and html page where the image is the only thing in the body.
