How to show binary picture in fckeditor?

I have saved a picture into database,such as oracle blob.I want to get this picture from database and show it in fckeditor.I can get this picture from database,and show it in a jsp,like follows:

Blob photo = zp.getPic();
InputStream in = photo.getBinaryStream();
OutputStream out = response.getOutputStream();
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) != -1) ...{
   out.write(buf, 0, len);
}
in.close();
out.close();

But I don't know how to show it in fckeditor.How to solve above question?

Thanks in advance!
