Actually, there is an easier way. Since SQL Server 2005,BLOBS are discouraged. You now have VARCHAR(MAX) which can store character data up to 2 GB. If you want to store images, place it on a richtextbox. Get the formatted text by:
String image_binary = richTextBox1.Rtf;
This will translate the image into a richtextformat - a format that stores images in text. You could now place the image_binary like any other String and retrieve it. It could now be placed on another richTextBox.
