Broken images in vaadin version 7.6.3

Hello.
My problem is described bellow.

When I scroll to the bottom of table and table loads it content, my images( images from StreamResource that are Embedded, i stored my images as blob in database) get broken.

First rows of table that contains Embedded images are shown just fine, but when i scroll down, the pictures that looks fine get broken.

getAllPartners method (here i load blob image from database):

public static Vector<PartnerDto> getAllPartner() {
            Vector<PartnerDto> result = null;
    
            PreparedStatement st = null;
            Connection conn = null;
            ResultSet rs = null;
            try {
                conn = Connect.getConnection();
                String sql = "select part_id,name, surname, picture from partner order by name, surname ";
                st = conn.prepareStatement(sql);
                System.out.println(sql);
                st.execute();
                rs = st.getResultSet();
                result = new Vector<PartnerDto>();
                while (rs.next()) {
                    PartnerDto dto = new PartnerDto();
                    dto.setPart_id(rs.getInt("part_id"));
                    dto.setName(rs.getString("name"));
                    dto.setSurname(rs.getString("surname"));
                    Blob imageBlob = rs.getBlob("picture");
                    if(imageBlob!=null){
                        InputStream binaryStream = imageBlob.getBinaryStream(1, imageBlob.length());                
                        dto.setPicture(binaryStream);
                    }else{
                        dto.setPicture(null);
                    }
                    result.addElement(dto);
                }
            } catch (SQLException e) {
                result = null;
                e.printStackTrace();
                System.out.println(e);
            } finally {
                Connect.closeConnection(rs, st, conn);
            }
            return result;
        }

My table (tPartners) initalization:     
           

tPartners.addContainerProperty("Slika uporabnika", Embedded.class, null);
            tPartners.addContainerProperty("Ime", String.class, null);
            tPartners.addContainerProperty("Priimek", String.class, null);
            tPartners.addContainerProperty("Rojstni datum", String.class, null);
            tPartners.addContainerProperty("Rojstni kraj", String.class, null);
            tPartners.addContainerProperty("Naslov", String.class, null);
            tPartners.addContainerProperty("Pošta", String.class, null);
            tPartners.addContainerProperty("Emšo", String.class, null);
            tPartners.addContainerProperty("Šola", String.class, null);
            tPartners.addContainerProperty("Razred", String.class, null);
            tPartners.addContainerProperty("Poklic", String.class, null);
            tPartners.addContainerProperty("Telefon", String.class, null);
            tPartners.addContainerProperty("Mail", String.class, null);
            tPartners.addContainerProperty("Klubska številka", String.class, null);
            tPartners.addContainerProperty("Številka kartice", String.class, null);
            tPartners.addContainerProperty("Datum včlanitve", String.class, null);
            tPartners.addContainerProperty("Opomba", String.class, null);
            tPartners.addContainerProperty("File type", String.class, null);
            
            tPartners.setSelectable(true);
            tPartners.setImmediate(true);

Code bellow shows how i *load images* in table:

//get all partners
                 Vector<PartnerDto> vResutl = DBLogika.searchPartner(text);
                
                for (int i = 0; i < vResutl.size(); i++) {
                    //class that represent PartnerDto
                    PartnerDto dto = vResutl.elementAt(i);
                    
                    String bd = "";
                    String din = "";
                    
                    if (dto.getBorn_date() != null) {
                        bd = sdf.format(dto.getBorn_date());
                    }
                    
                    if (dto.getDate_in() != null) {
                        din = sdf.format(dto.getDate_in());
                    }
                    
                    Embedded emb=new Embedded();
                    
                    StreamResource.StreamSource source = new StreamResource.StreamSource() {
                        
                        public InputStream getStream() {
                             //get inputstream from database, i save my image as longblob in database
                             return dto.getPicture();
                            
                        }
                        
                     };
                     
                   //uniq name for every file
                   SimpleDateFormat df = new SimpleDateFormat("yyyyMMddHHmmssSSS");
                    String filename = "mytablepic" + df.format(new Date()) + ".png";
                    
                   StreamResource sourceone=new StreamResource(source, filename);
                  
                   emb.setHeight("200px");
                   emb.setWidth("150px");
                   
                   emb.setSource(dto.getPicture()==null? new ThemeResource("images/user_pic.jpg"): sourceone); 
    
                     tPartners.addItem((new Object {emb, dto.getName(), dto.getSurname(), bd, dto.getBorn_place(), dto.getAddress(),
                                dto.getPostDto().getPostName(), dto.getEmso(),
                                dto.getSchool(), dto.getPartClass(), dto.getJob(), dto.getPhone(),
                                dto.getMail(), dto.getClub_number(), dto.getCard_number(),
                                din, dto.getDesc(),dto.getFileextention()}), dto);
                     
                }

What i am doing wrong ? 

Two images that shows my problem:

https://www.dropbox.com/s/y9gnoxbsgvc2jm7/picture.png?dl=0
 https://www.dropbox.com/s/q19hsiq3fb2vto4/picturenormal.png?dl=0

I am running my application on localhost on tomcat v8.0 server.

When i inspect images in firefox with firebug, it tells me: Could not load the image. 

Somehow when i scroll, and tables need to load it contant, images get broken... 

How could i solve this problem? Please help me :-)

Tnx you very very very much ;-) God bless you. Now everything is working fine.
