Question

I’m trying to show an image on my Image control but it isn’t working. I’m using it as a screenshot preview basically. I have the bitmap save to the Images folder in the server path, and then I set the ImageUrl for the control to that saved image location. Here is the code I have. This code executes on a button click:

img.Save(Server.MapPath("~/Images/") + "test.png", ImageFormat.Png);
Image1.ImageUrl = Server.MapPath("~/Images/") + "test.png";
Image1.DataBind();

No exceptions are caught, and the image is saving correctly in the path.

Answer 1

You can’t use Server.MapPath for URL’s, change to this (presuming that images folder is in the root folder of your application):

Image1.ImageUrl = "/images/test.png";

update:

As Graymatter suggested ih comments that should be :

Image1.ImageUrl = "~/images/test.png";

I overlooked that we are talking about Image server control
