you need to upload image using FileUpload control

in your aspx

Upload Image

onclick="BtnUpload_Click"/>

in your code
protected void BtnUpload_Click(object sender, EventArgs e)
{
if (UserImgFileUpload.PostedFile.ContentLength > 0)
{
var userImagePath = Server.MapPath("Images");
var fileName = UserImgFileUpload.FileName;
var path = userImagePath + fileName;
if (File.Exists(path))
{
File.Delete(path);
}
UserImgFileUpload.PostedFile.SaveAs(path);
}
}
