I have got same problem some time back so i got a work around for this problem i hope this will work for you too.

1) First i created the web app with the service reference of the created web service suppose Barcode39 is service so add the reference to the web application. 2) Then write the code behind using service client and call the method to create the barcode image in that code by passing the request variables values 3) Now give the link of that page as the URL to the image expression along with setting the image type as "EXTERNAL" and pass the values to the URL as request variables as

 "http:\\localhost:2310\BarcodeImage.aspx?data=" +(Parameters!YourParamtere.Value)

And one thing instead of returning the Image from the service try returning the byte array using stream and .ToArray() method that would be the best practice.Let me know if any problem.
