Answer 1

you can use plain old javascript window.location.href = "http://stackoverflow.com"; to redirect the client to a new page..

Answer 2

Use URLFOR() with apex:outputLink

Refer apex:outputLink

target - The name of the frame where the resource retrieved by this command link is displayed. Possible values for this attribute include "_blank", "_parent", "_self", and "_top". You can also specify your own target names by assigning a value to the name attribute of a desired destination.

<apex:outputLink target='_self' value='{!URLFOR($Page.Page2, null, ['id'=id])}'>
    =<apex:image style="height:25%;width:60%" value="!$Resource.apply1}"/>  
</apex:outputLink>
