HI Guys
I am trying to insert a default image into the database if the user does not pick any image in the Fileupload.I am trying to use the following code to upload the default image ..but I am not getting ..Please see the code and tell how to read the image...

UriBuilder uBuilder = new UriBuilder();
uBuilder.Scheme = HttpContext.Current.Request.Url.Scheme;
uBuilder.Host = HttpContext.Current.Request.Url.Host;
if (HttpContext.Current.Request.Url.Port != null)
uBuilder.Port = HttpContext.Current.Request.Url.Port;
uBuilder.Path = HttpContext.Current.Request.ApplicationPath;
String buildUrl = uBuilder.ToString();
buildUrl = buildUrl + "/web/images/ina.jpg";//localhost image
System.IO.Stream iStream = new System.Net.WebClient().OpenRead(buildUrl);
What can I do after this.....
This is the code for If user pick the image through FileUpload
System.IO.Stream inputStream = PhotoUpload.PostedFile.InputStream;
int imageLength = PhotoUpload.PostedFile.ContentLength;
byte[] imageBinary = new byte[imageLength];
int inputRead = inputStream.Read(imageBinary, 0, imageLength);
byte[] imageData = imageBinary;

Thanks&Regards
Arun

you can check whether fileupload control is empty or not.
by this you can insert default images if he doesnt selects the image.

Hi Arun,
You can check with this if loop

if(uBuilder.PostedFile !=null && uBuilder.PostedFile.FileName!="")
{
/* Get the default image here*/
}
