How To Properly Update Components in a Form - ajax

Question

I have a bunch of panels in my form which display images but i have a problem with getting the images to update(load next set of images) with a click of a button. I have tried using the ajax="false" method but this erases the all the variables in the form e.g(the urls used to load the images ) This is my button:
<div style="position : absolute; right:400px; top:1500px" >
<p:commandButton value="Confirm" id="Confirm" actionListener="#{con.confirmButton}" oncomplete="PF('panelP').hide()" ajax="false" />
</div>
The panels and Confirm button are stored in the form like:
<h:form id="form">
<p:galleria id= "ISSimage" style="position : absolute; left:50px; top:550px" value="#{con.gallery}" var="image" panelWidth="500" panelHeight="313" showCaption="true">
<p:graphicImage value="#{image}" alt="Image Description for #{image}" title="#{image}"/>
</p:galleria>
<f:view contentType="text/html">
<p:panel id="satImage" style="position : absolute; right:50px; top:550px" panelWidth="500" panelHeight="400">
<p:gmap id="satview" center="#{con.lati}, #{con.longi}" zoom="6" type="SATELLITE" style="width:600px;height:400px" model="#{con.simpleModel}" />
</p:panel>
</f:view>
I try to store a list of all the image
Is there a way to properly load the next set of images with the click of the confirm button without erasing the image variables?
MY BEAN is 300 lines so i only limited to showing the relevant parts . here it is:
public void confirmButton(ActionEvent actionEvent){
//setting Next Image
//add the point depending on which panels are open then reset the panel booelan values
gallery = new ArrayList<String>();
candidates = new ArrayList<String>();
Connection conn = null;
PreparedStatement stmt = null;
//Statement stmt1 = null;
ResultSet rs = null;
//gallery.clear();
try{
gallery = new ArrayList<String>();
conn = DriverManager.getConnection(CONN_STRING,USERNAME,PASSWORD);
stmt = conn.prepareStatement(op);
//stmt.setString(1, oldconsole);
//stmt.setString(2, oldconsole);
stmt.setDouble(1, oldlati);
stmt.executeUpdate();
stmt = conn.prepareStatement("SELECT * FROM `ISS` WHERE taskinfo__citylat = (SELECT taskinfo__citylat FROM `ISS` LIMIT ?,1)");
int rdmnum = randomise();
stmt.setInt(1, rdmnum);
rs = stmt.executeQuery();
while(rs.next()){
String issimg=rs.getString("taskinfo__link_small");
gallery.add(issimg);
//ADDS IMAGES TO GALLERIA
excl_num = rs.getInt("rownum");
excluded.add(excl_num);
//ADDS ROWNUMBERS TO EXCLUDED ARRAY SO THEY DONT GET CALLED AGAIN.
lati = rs.getFloat("taskinfo__citylat");
longi = rs.getFloat("taskinfo__citylon");
oldlati=lati;
}
catch(SQLException e){
System.err.println(e);
}
public float getLati(){
return lati;
}
public float getLongi(){
return longi;
}
public double getOldlati(){
return oldlati;
}
public double getOldlongi(){
return oldlongi;
}
