WhatsApp contact's icon not showing
Maybe you are talking about the contact picture. The contact picture is only visible if the user has specified it. 

By default you can have contacts sync with all account but Profile pictures will not be sync'd in app. Each app may have different profile pictures.  

Try this: go to sdcard -&gt; whatsapp -&gt; profiles Pictures-&gt;

Here you should see what and how many pictures are there. Only those will be shown in WhatsApp contact list.
