Using HttpHandler for Images - can't print images frm chrome

Question

Hi,

I'm using an HttpHandler to display images from memory ... which is working fine.

The image is displayed as a .png format in a popup window.

My problem is printing the image from chromeWeb Browser using the popup menu displayed after doing a right-click, selecting 'Print Picture'.

A blank page is being printed ... i.e. No Image, just the url and date on the bottom of the page and the page number on the top.

I have also tried this with the image formatted as .jpg, with the same result.

Neither 'Print Picture' or 'E-mail Picture' is working properly. With E-mail, an email is created, but no image.

The Image Control's ImageUrl="~/ImageHandler.ashx"

The code used to update the image in the ImageHandler is located in the ProcessRequest function:

if (context.Request.QueryString["z"] != null)

{

SecureQueryString qs = new SecureQueryString(context.Request.QueryString["z"]);

if (!String.IsNullOrEmpty(qs["icontable"]) && !String.IsNullOrEmpty(qs["iconcolumn"]) && !String.IsNullOrEmpty(qs["iconid"]))

{

ServiceClient webservice =WCF.GetService();

byte[] imgReceipt;

try

{

SQLCommand cmd = new SQLCommand();

cmd.StoredProcedureName = "JSN_GENERIC_ICON_LOADER";

cmd.Parameters = new List<SQLParameter>();

cmd.Parameters.Add(new SQLParameter() { ParameterName = "@TABLENAME", Value = qs["icontable"] });

cmd.Parameters.Add(new SQLParameter() { ParameterName = "@COLUMNNAME", Value = qs["iconcolumn"] });

cmd.Parameters.Add(new SQLParameter() { ParameterName = "@ROWID", Value = int.Parse(qs["iconid"]) });

using (DataSet ds = webservice.ExecuteDataSet(cmd))

{

if (ds.Tables.Count > 0 && ds.Tables[0].Rows.Count > 0)

{

DataRow dr = ds.Tables[0].Rows[0];

imgReceipt = DBHelper.GetDBImage(dr, "ICONDATA");

MemoryStream stream = new MemoryStream(imgReceipt);

if (stream.Length > 1)

{

context.Response.ContentType = "image/png";

context.Response.Cache.SetCacheability(HttpCacheability.Public);

context.Response.BufferOutput = false;

const int buffersize = 1024 * 16;

byte[] buffer = new byte[buffersize];

int count = stream.Read(buffer, 0, buffersize);

while (count > 0)

{

context.Response.OutputStream.Write(buffer, 0, count);

count = stream.Read(buffer, 0, buffersize);

}

}

}

}

}

catch

{

context.Response.StatusCode = 404;

context.Response.StatusDescription = "File Not Found";

context.Response.Flush();

}

finally

{

qs = null;

}

}

else

{

context.Response.StatusCode = 400;

context.Response.StatusDescription = "Invalid Request";

context.Response.Flush();

}

}

I would greatly appreciate any thoughts on how to get print to work.

Thanks.
