JavaScript - Help On Random No Pinpad

I've looked for a solution to this issue, but it seems like a little different scenario than other situations.

I made a system for generating friend requests on Facebook. I have a grid that is 6 x 3, for a total of 18 cells. Each cell has a picture in it, and the picture is linked to the Facebook friend request page. My problem is that since each cell is populated at random from the array, I'm getting lots of repeats. For example, some picutures are in 5 cells, and some are in none. I'm trying to figure out how to make it so that once a picture is used once in the grid, it does not get used again in the same grid. I still want every cell filled at random on each page load, I just want to prevent the repeating.

Here's my current code:
Code:

<script type="text/javascript">

Any suggestions?
Thank you!

Hi,

I'm not much of a programmer, I have this script for randomly rotate a bunch of pictures.
What do you change to make to change from one another, not random?

Thanks
Denny

<script language="javascript">

var delay=5000 //set delay in miliseconds
var curindex=0
var i = 0
var randomimages=new Array()

randomimages[0]="...image01.jpg"
randomimages[1]="...image02.jpg"
randomimages[2]="...image03.jpg"
randomimages[3]="...image04.jpg"
randomimages[4]="...image05.jpg"
randomimages[5]="...image05.jpg"

var preload=new Array()

for (n=0;n<randomimages.length;n++)
{
preload[n]=new Image()
preload[n].src=randomimages[n]
}
i = Math.floor(Math.random()*(randomimages.length))
document.write('<img border=2 name="defaultimage" src="'+randomimages[i]+'">')
function rotateimage()
{
if (curindex==(tempindex=Math.floor(Math.random()*(randomimages.length))))
{
curindex=curindex==0? 1 : curindex-1
}
else
curindex=tempindex
document.images.defaultimage.src=randomimages[curindex]

}
setInterval("rotateimage()",delay)
</script>

hey. im working on a facebook app..
this is what i got so far.
PHP Code:
<script language="JavaScript">

var theImages = new Array()

}

<script language="JavaScript">

showImage();

now i want that the app posts the random image automaticlly to the useres timeline.. for example: if the random image is theImages [3] then it should post the image theimage [3] to the users timeline.. i see alot of facebook apps doing this.. thanks in advance

I've started studying JavaScript recently. The following simple scenario from the Russian textbook cannot be implemented on my PC.
Code:

<HTML>
<HEAD>
<TITLE>Object Math Example</TITLE>

</HEAD>

<BODY>
<h1>Object Math Example</h1>
<p>Насколько случайны числа, полученные генератором случайных чисел? Подсчитаем среднее 5000 случайных чисел.</p>

<SCRIPT LANGUAGE="JavaScript">
total = 0;
for (i = 0; i<5000; i++)  {

        num = Math.random();
        total += num;
        document.status = "Generated " + i + " numbers";
      }

average = total / 5000;
average = Math.round(average * 1000 / 1000);
document.write("<h2>" arithmetic mean of random numbers  + average + "</h2>");

</SCRIPT>

</BODY>
</HTML>

I just typed the script char by char. I use Firefox browser, v.3.5.7. The error console does not display any mistakes.
Please, explain me what is wrong in the code.

I recently decided to organize my bags on http://www.coach-bag.org/category-1-...+Handbags.html - I labelled all the boxes, making sure each box had only one purse in it's dustbag and organized by season. I have 14 at the moment - 4 for Spring/Summer and 10 for Fall/Winter. I actually (OK, this is going to sound oh-so-anal) did up a schedule by week and purse and will change over every Sunday morning. I did the schedule until the end of January and each purse only gets into rotation twice - that's not very much and I hate the idea of things not getting adequate usage. And it really got me thinking as to what else I really need - but then again, who needs 14 purses, right? We all know this isn't about need.

So that got me thinking about something mentioned in another thread. I have a price point in my head that I'm not comfortable going over per bag and it's $400. I had a brief moment when I considered the floral Sophia, but once I saw the modelling shots and figured out she was too big, I dismissed it and was a little relieved to do so.

But with 14 bags not getting into rotation that often, I'm wondering if I should change my mindset to buy 2-3 more expensive bags per year rather than what I did in this first 14 months of Coach collecting - which was buy 14 (plus all the wallets, scarves, keyfobs and other goodies). If I do that again this year, that means I could be close to 30 purses, and honestly, I'm not comfortable with that many bags - not from the financial standpoint - just the usage or lack thereof standpoint.

It seems like a lot of you ladies do spend the big bucks on bags - and lots of them - and that's great. I'm not independently wealthy, and I refuse to run a credit card balance for purses, so I only buy what I can afford and usually wait for PCE. And I guess I love a deal more than I love any individual purse, so it will really be a change in mind set for me to pay maybe $1000 for a bag maybe 2-3 times a year instead of what I've done this past 14 months where I bought 14 bags - mostly at 25%, 40% or outlet pricing.

I know for some of you ladies who have DOZENS of bags, my 14 must seem minuscule and you probably think I'm nuts for thinking so hard about it - but I need to find the right balance, and I guess I'm just trying to sort that out.

Does anyone else think so hard about this silly little topic or is it just me?

Thanks for letting me unload my thoughts here!!
