How to display image in database using html or php

i've try already to work this thing but i can't do it. anyone that can help me or give me any example or reference to resolve my problem to retrieve or display image(blob) from database. hope that all of you help me

Using JHeadstart, you can display a BLOB column from the database in HTML, by way of ADF. Check out the JHeadstart Tutorial at http://www.oracle.com/technology/products/jdev/tips/muench/jhstutorial/index.html to get started, then do the same for your own database tables that include the BLOB column. JHeadstart will take care of rendering it as a file upload or image, depending on the display type you set at the attribute level.
Hope this helps,

I asked a similar question once and the answer I got was - Don't.
Instead, store the images on a drive somewhere and store the path in the database.
But I'm no expert - that's just what I was told by someone who does this kind of stuff a lot.
Hope that helps.

How to display information from database using drop down list in JSP?

Hi all.
Like the tile above suggest, I'm having difficulty in obtaining the data as well as displaying them in a drop down list.
For example: If i were to have the following in my database:
SerialNo Food
1 Bread
2 Milk
3 Butter
The drop down list should look like the following:
[Bread][\/]
[Milk]
[Butter]
How do i go around coding it in JSP?
Thanks in advance.

How to store images in database and retrieve them back to page?

Well I don't know how to store an image file to a database (say MSSQL) from the JSP and retrieve it back whenever needed and put it on the JSP page? Please help me.

I am not sure how to store images in database but what you can do is store the image into particular folder using FileOutputStream and its unique name into the database...and than retrieve it from the folder using that name retrieved from database...

How to display image?

Hi all,
How to display image from the database table in the adobe form by using web dynpro abap?
I want to display image in the adobe interactive form by using web dynpro abap.
Please help me.
Regards,
srini

Hi Srini,
If you go through the article you might have seen the following piece of code
*** Send the values back to the node
lo_el_z_if_test_cv->set_static_attributes(
EXPORTING
static_attributes = ls_z_if_test_cv ).
" here ls_z_if_test_cv has the image in XSTRING format which has beeen retrived using METHOD get_bds_graphic_as_bmp of CLASS cl_ssf_xsf_utilities
" In your case you need to just use the select query n fetch it from your table; ( provided your image is store in XSTRING format )
How is your image stored in your database table ?

Radhika.

How to display images and information

how to display images and information(e.g. like questions) on a jsp page that stored in a database

Look As far as i can see....
Utlimately every file could be expressed as a bytes buffer.
so say if you have a bean called Choice Bean which is expressed as
public class ChoiceBean{
   private String choiceid;
   private String choicedesc;
   private byte image[];
   public void setChoiceId(String choiceid){
          this.choiceid = choiceid;
    public String getChoiceId(){
           return this.choiceid;
      public void setChoiceDesc(String choicedesc){
           this.choicedesc = choicedesc;
       public String getChoiceDesc(){
           return this.choicedesc;
       public void setImage(byte image[]){
              this.image = image;
         public byte[] getImage(){
              return this.image;
}QuestionList.java:
===============
public class QuestionList{
     private List<ChoiceBean> choicelist;
      /*Other member variable declarations*/
       public List<ChoiceBean> getChoiceList(){
                /*Custom code where you may build the list by querying the DA layer*/
                 return this.choicelist;
     public int search(String choiceid){
             int index = -1;
             for(int i =0 ; i < this.choicelist.size() ; i++){
                    ChoiceBean cb = this.choicelist.get(i);
                     if(cb.getChoiceId().equals(choiceid)){
                            index = i;
                            break;
             return index;
    /* Other member method declarations */
}and you are retreving List<ChoiceBean> from DB using your query & have created a session attribute / <jsp:useBean> named ChoiceList
NOTE: sometimes your application server can go out of bounds as you are consuming a lot of memory by creating an arraylist object.
use the following methodology to display images & choices
sample.jsp:
=========
<jsp:useBean id="QuestionList" class="com.qpa.dao.QuestionList" scope="session"/>
<TABLE>
<%
/* QuestionList.getChoiceList() is a method which fetches data from the DB & returns it in form of List<ChoiceBean> */
List<ChoiceBean> choicelist = QuestionList.getChoiceList();
for(int i =0 ; i < choicelist.size() ; i++){
%>
<TR>
<TD><%!=choicelist.get(i).getChoiceId()%></TD>

<TD><IMAGE src="ImageServlet?choiceid=<%!=choicelist.get(i).getChoiceId()%>"/> </TD>
<TD><%!=choicelist.get(i).getChoiceDesc()%></TD>
</TR>
<%
%>
</TABLE>
<%
    session.remove("QuestionList");
%>
NOTE: usage of JSTL or any other custom built tag-libraries makes life more simpler in the following case
ImageServlet.java:
===============
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        byte buffer[] = null;
        HttpSession session = request.getSession(false);
        /*getting the QuestionList from the session*/
        QuestionList ql = null;
        String choiceid = new String("");
        try{
             choiceid = request.getParameter("choiceid");
             /*getting the QuestionList from the session*/
            ql = (QuestionList) session.getAttribute("QuestionList");
        } catch(Exception exp){
        if(choiceid.equals("") == false && ql != null ){
            List<ChoiceBean> clist = QuestionList.getChoiceList();
               assuming that you have created a serach method which searches the entire choice list and would give you
               the index of that object which is being refered by unique choiceid and returns -1 if not found
            int index = QuestionList.search(choiceid);
            if(index != -1){
               ChoiceBean cb = clist.get(index);
               buffer = cb.getImage();
        if(buffer != null){
             // assuming that we have stored images in JPEG format only
             JPEGImageDecoder decoder = JPEGCodec.createJPEGDecoder(new ByteArrayInputStream(buffer));
             BufferedImage image =decoder.decodeAsBufferedImage();
             response.setContentType("image/jpeg");
             // Send back image
             ServletOutputStream sos = response.getOutputStream();
             JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(sos);
             encoder.encode(image);
        } else {
           response.setContentType("text/html");
           response.getWriter().println("<b>Image data not found</b>");
}However,i still feel there are few loopholes with this approach where Application Server can eat up a lot of heap space which may result in outofmemorybound exception.
Hope this might help :)
REGARDS,

How to display images on my internal isight?

Hi,
I just bought the new iMac 2 gig dual. Running on 10.5.2.
I wanted to know how to display images on my screen during a video conference chat without resorting to holding up a print out to the camera? I need something where I can switch from video mode to image mode and show a single image at a time if I need to. All that while still talking of coarse. If it isn't possible with my iSight software, can you point me to other software I can download and still use my built in cam?
I hope I was clear enough in asking this.
Thanks
Liban

Welcome to Apple Discussions, Liban
iChat can do what you want, but I do not know of any web-based video chat site that can.
Look for Help or Support information on the site you are using or ask the Webmaster if his site has the capability to do what you want.

How to display RTE item in a HTML region

I have a process that is populating a hidden item with a RTE item from another page. I need to display this in its formatted state. I am using an HTML region to display this item but the page shows HTML tags instead of rendering them. I have tried both options under html region (escape special characters and plain HTML text).
Can someone please help me to display this formatted RTE item on a page? Btw...I am using APEX 4.0.
Thanks.
