Hi,

Use the below controller and Visual force page  :

 

Apex Class

Public Class displayImageExtension {

    String recId;
    
    public displayImageExtension(ApexPages.StandardController controller) {
        recId = controller.getId();    
    }
    
    public String getFileId() {
        String fileId = '';
        List<Attachment> attachedFiles = [select Id from Attachment where parentId =:recId order By LastModifiedDate DESC limit 1];
        if( attachedFiles != null && attachedFiles.size() > 0 ) {
            fileId = attachedFiles[0].Id;
        }
        return fileId;    
    }
}

 

 

Visual Force Page

 

<apex:page standardController="Account" extensions="AccountImageController">
<apex:form >
<apex:image url="/servlet/servlet.FileDownload?file={!FileId}"/>
</apex:form>
</apex:page>

Hello,

 

Please refer the following example :

 

Controller :
=================================

public with sharing class ImageController {
 public String imageURL{get;set;}
   
  public ImageController()
  {
    imageURL='/servlet/servlet.FileDownload?file=';
    List< document > documentList=[select name from attachment where 
                                    Name='SamplePic'];
   
    if(documentList.size()>0)
    {
      imageURL=imageURL+documentList[0].id;
    }
  }
}
 
Visual Force Page :
=====================

<apex:page controller="ImageController" showheader="false" sidebar="false">

Hi Puja_mfsi,

I borrowed your code and it works well in my Sandbox.  Thank you.

Just went to move the change set to Production and got this error:

"This change set contains components that require the "30.0" or higher platform version."

Thank you for your help!

Hi Hobie,

Sounds like your sandbox is on a 14 instance and your live org is on 13. 
If you change the API down to 29 ofor example and try again this should do it.
(Open the class, press edit, version settings Salesforce.com-API)

thanks

Can we use the same approach to show Attachments related to Account object to Partner Portal and Customer Portal users?

Why don't we use the standard way? We cannot guarentee that Salesforce will keep the URL /servlet/servlet.FileDownload?file= for ever. If this changes evrything will break. 
We have $Action (https://www.salesforce.com/us/developer/docs/pages/Content/pages_variables_global_action.htm) for this purpose.

Use  <apex:image url="{!URLFOR($Action.Attachment.Download, AttachemntId)}" /> instead. The standard way.
