How can I show image file from Amazon S3 in asp.net mvc?

Question

I need to show image(thumbnail) in view page using controller/action.(like: /Image/Thumbnail) I can send image file that is stored locally by calling the method in controller.

// sample code
public FileResult Thumbnail()
{
    // get image
    Stream outFile = System.IO.File.Open("c:\\test.jpg", FileMode.Open);

    // send image
    return File(outFile, "image/jpeg");
}

How can I send image file that is stored in Amazon S3 ?

Can I use Amazon S3 URL in the above method to return image ? --> http://bucketname.s3.amazonaws.com/test.jpg?AWSAccessKeyId=AKIAIDLH65EJ6LSWERDF&Expires=1266497098&Signature=lopDEDErjNLy2uz6X6QCNlIjkpB0%3D

Thanks

You can return a redirect result:

public ActionResult Thumbnail()
{
    return Redirect("http://domain.com/test.jpg");
}

If the url points at the image file then it will work. Of course you shouldn't present the url of this action to user but use it in some other view as <img> src attribute value:

<img src="<%= Url.Action("Thumbnail", "ControllerName") %>" />
