How can add a images file to anothere image file

Question

hi
Requirement is: i have one image in data base , i is show to user in my application
know we want add another image file in to a current image file (just append)
at end .
i was tried with following code below
i was read the previous(Old) image content from the data base and placed into c:\\ReArchive\\test_content.tiff
ResultSet rs2=dbBean.getSQLRows("select binarycontent from ContentVersion where contentindex="+IndexValue+"");
byte[] bTempData_content=new byte[65536];
while(rs2.next()){              
File f = new File("c:\\ReArchive\\test_content.tiff");
f_content.delete();
f_content.createNewFile();
FileOutputStream dest_contentVersion = new FileOutputStream(f_content);
while(rs2.next()){              
InputStream is_content=rs2.getBinaryStream("Binarycontent");
nActualRead_content=is.read(bTempData_content,0,65536);
while(nActualRead_content>0)
dest_contentVersion.write(bTempData_content,0,nActualRead_content);
nActualRead_content=is.read(bTempData_content,0,65536);
Then i was took New image file from data base and place in to c:\\ReArchive\\test.tiff");
int nActualRead=0;
ResultSet rs1=dbBean.getSQLRows("select * from Object_Store where Barcode_ID='"+strBar_Code+"'");
byte[] bTempData=new byte[65536];
File f = new File("c:\\ReArchive\\test.tiff");
f.delete();
f.createNewFile();
FileOutputStream dest = new FileOutputStream(f);
while(rs1.next()){
InputStream is=rs1.getBinaryStream("Obj_Content");
nActualRead=is.read(bTempData,0,65536);
while(nActualRead>0)
dest.write(bTempData,0,nActualRead);
nActualRead=is.read(bTempData,0,65536);
then i tried add two images by converting InputStream to String and i am trying add to images
but i was failed ,i think i am in not correct way , how can i solve this problem
thanks advance
