Problem with iterator and images

Hi all, before to start, i want say sorry for my bad english.
I am developing an easy social network for a university project

Every User has an image for the profile.

I want to list all friends, and i want display Name, Surname and the image.
So i have an action that retrieve the list of friends:

public String list() {
Utente utente;
utente = (Utente) session
.get(AuthenticationInterceptor.authenticationSessionField);
utenteDao.update(utente.getId());
setListaAmici(utente.getListaAmici());
System.out.println("total friends: " + listaAmici.size());
return SUCCESS;
}

Now I have a list of Users. So in my jsp:

friends : <s:property value="listaAmici.size" />
<br />
<s:iterator value="listaAmici" var="amico">
<s:url value="%{#amico.fotoProfilo.path}" />
<img src="" width="200" />
<s:property value="#amico.nome" /> <s:property value="#amico.cognome" />
</s:iterator>

I don't know how do it!
The database save the name of the image.

Sorry for my bad english.
Thanks
Fabio

I resolved!!

<s:iterator value="album.listaFoto" var="foto">
<s:url id="_foto" action="show" namespace="/foto">
<s:param name="foto.id" value="#foto.id"/>
</s:url>
<s:url value="%{'/images/'+ #foto.path}" includeParams="none"
id="img_foto"></s:url>
<div class="amico">
<img src="<s:property value="img_foto"/>" width="50" /><br />
<s:a href="%{_foto}"><s:property value="#foto.path"/></s:a>
</div>
</s:iterator>
