A title can only have text, so you need to parse it out.
document.title = document.title.replace(/\d+$/, "new value");

title can't be set like that, it's not a child of .html
some thing like
var num = 3;
document.title = "foo "+num
to set the title, then reuse num for these photoids.

Use the jQuery onDocumentReady syntax:
$(function () {
var elements = $('.contains_photoid');
elements.html(elements.html().replace("3", "4"));
$(document).attr('title', $(document).attr('title').replace("3", "4"));
});
You can't see the title change in this example, but that is the syntax. See Changing the page title with Jquery
The "3" and "4" can be changed to anything, so you can create the page with a unique character string in place of the real ID in order to easily replace it if it appears in text with numbers already in it.

I threw it in there because that's closer to changing all occurences "at the same time" than if it wasn't. – JustcallmeDrago Jun 07 '14 at 01:02

I see. I missed that you were also setting the other elements at once. – cookie monster Jun 07 '14 at 01:03

Javascript
var photoID = 355; //this assumes you have some code where you set this photoID value
var title = document.title;
title = title.substr(0,title.lastIndexOf('#')+1);
document.title = title+photoID;
See this fiddle for proof: http://jsfiddle.net/xrkhA/
(I used a div content because you can't use title in jsfiddle)

You can either use, but $('title') will fail in IE8
document.title="new title";
or
$('title').html('new title');
or
$(document).attr('title','new title');
