Hi! Do you want to display an image from client machine (before uploading), or image from server (after uploading)?

ok, then you need to set Url to local path, while System.IO.Path.GetFullPath(this.AsyncFileUpload.PostedFile.FileName) will give you path on server, which is not the same

Hi You cannot do that in server code for security reasons, the only chance is to use javascript. Look following sample: http://www.daniweb.com/web-development/javascript-dhtml-ajax/threads/114822

Hi! Do you use AsyncFileUpload from ajax toolkit? Do you want to display preview after file is uploaded to server?

This question is a duplicate of this one:

You would need to save the image to a directory that the web application has permission to read from then assign the saved image path to the source attribute of the Image control.

Example: You have a folder inside your web application that you save your uploaded images to called UploadedImages. The folder has read/write privileges for IIS_IUSRS. Get the path to that folder:

string APP_PATH = Server.MapPath(System.Web.HttpContext.Current.Request.ApplicationPath) + "images\\";

Save your uploaded image to it:

myImage.Save(APP_PATH + "facebook.png");

Assign the image path to the source attribute of the Image control:

imgLoading.ImageUrl = "~/images/facebook.png";
