Image Retrevial From Database throws error

Question

Can anyone point out what i'm doing wrong with the code below please..
It all works perfectly and returns the image. The probelm is that it causes
java.lang.IllegalStateException: getOutputStream() has already been called for this response
to be thrown in the site's logfile.
It all works perfectly by causes the log file to fill up as visitors access the image.

<%@ page import="java.sql.Connection" %>

statementgalleryimage = connectiongalleryimage.createStatement();
ResultSet rs = statementgalleryimage.executeQuery("select main_image from galleryobj where galobj_id=5 and rec_status='ACTIVE'");
rs.first();
byte[] bytearray = new byte[4096];
int size=0;
sImage = rs.getBinaryStream(1);
response.reset();
response.setContentType("image/jpeg");
response.addHeader("Content-Disposition","filename=getimage.jpeg");
OutputStream outputStream = response.getOutputStream();
while((size=sImage.read(bytearray))!=-1) {outputStream.write(bytearray,0,size);}
} catch (Exception e) {
out.println("<!-- Error getting requested image: "+e+"-->");
} finally {
response.flushBuffer();
sImage.close();
statementgalleryimage.close();
connectiongalleryimage.close();
