Hi,
Image1.ImageUrl will take relative Url like "~/MY_IMAGE.JPG" so after uploading assign relative URl to your image control, that will do the trick.

Hope this will help.

Not to hijack or anything, but I'm doing something not disimilar and wonder if this is more efficient than doing the for loop above, since the loop will run its entire course, even if the first extension hits.

string FileTypesString = ".gif.jpg.png.jpeg.";
Ext = Path.GetExtension(file.ToLower()) + ".";
if (!String.IsNullOrEmpty(Ext))
{
if (FiletypesString.Contains(Ext))
{
fileOK = true;

Try this,

C#

Image1.ImageUrl = "~/UploadedImages/" + FileUpload1.FileName;

Solution 3

Here is one sample working code snippet. You have to provide Relative paths with ImageURL.

C#

protected void Button1_Click(object sender, EventArgs e)
   {
       if (FileUpload1.HasFile)
       {
           string filename = Guid.NewGuid().ToString() + ".jpg";
           FileUpload1.PostedFile.SaveAs(Server.MapPath("Images\\") +filename);
           aspimage.ImageUrl = "~/Images/" + filename;
       }
   }
