Help with reading a file from the middle tier and writting to database.

Using PJC's File Upload Utility I'am trying to upload a file(of any format) from the client's machine to the middle tier, from here I want to insert it to the database.

I did the above action(when I uploaded a image file from the client's machine), by using the Read_image_file on the form from the middle tier and I committed the form.

But unfortunately the Read_image file is only for the images and it does not read anything else from the middle tier.
Can anybody help regarding this.
thanks in advance.
