Just save the info to shared preferences, then use an if statement to load the shared preferences. as in

if (preferences == websiteOne){
//load shared preferences  for websiteOne here
} else {
// load shared preferences for websiteTwo here
}

If you have more than two websites, you can set up a switch/case

EDIT

switch (website){
case websiteOne:
// shared preferences for websiteOne
imageView.setImageResource(imageResourceFromSharedPreferences);
url.setText(urlFromSharedPreferences)
break;
case websiteTwo:
// shared preferences for websiteTwo
break;
}

Do that for all 10 websites

EDIT 2

to set up a default sharedPreferences, in your onCreate() of an early activity, you can use 

data = getSharedPreferences(filename, 0);
SharedPreferences.Editor e = data.edit();
        e.putString("website", websiteVariable);
        e.commit();

Do the same for the URL, and add these two variables SharedPreferences data; and public static String filename = "fileName";
