>OK, it would be basically in looks like the photo contest.

OK

>The admin would upload a pic of something and

OK

>below the pic they would have the option to set up to 5 prizes, so they would put in 1 to 5 prize descriptions.

I don't really understand it.
I can feel I am misudnerstanding the relationship between the pictures and the prizes.
I thought there was a definite relationship between a picture and it's prize but maybe I am wrong.
Maybe, a picture doesn't represent the prize at all.
Maybe, completely random pictures are fine because the prizes have nothing to do with the pictures.
Am I correct?

By the way, is there any case that a player doesn't win?
In other words, the player clicks a box, won't get any prize and
get a message like "You lose!"

>The front end would like something like the pic below.

OK

>Once a person has paid, if they paid for 3 boxes, they would be able to click on 3 different pics to reveal their prizes.

OK

>If admin set them to only work once they would say something like already won or something like that, if set to work several times they would go back to pics and the next prize in line would be there for the next player.

OK

>So in my example below I bought 6 tickets for $25, I would be sent to paypal and once I paid sent back to the page where I would click on 6 different boxes ...

I did research on this issue and found a few methods that are close to your ideas but they are not perfect.
I think I have to resort to a classic approach. My idea is using "a ticket #"

For example, this is the first screen you will see.
A player chooses the number of tickets to buy and clicks the buy button to go to PayPal checkout.






After paying thourgh PayPal, the player receives an email like this.

--------------------------------------------------
Thank you for purhcasing 6 tickets!
A ticket # has been issued.

Ticket #: T12345678
--------------------------------------------------

Then the player enters the ticket # in the page and clicks the submit button.








The script recognizes the ticket # and becomes ready to accept up to 6 clicks like












Is this OK with you?

>if the boxes are set to work more than once it would show me my prize and then go back to the pic (since I get an email that would be fine, so I could click it again or click a different one, does that explain it better?:

I'll just say OK for now. We can discuss it later because it's not so important.
