well, that's how the like of hot or not are set up too, but if you want to change the order, you'd open up /packages/contest/controllers/page_types/contest.php, and comment out line 56, which should look like this:

shuffle($contestEntryPages);

oops. looks like it's not going to be that easy. if you look below that, there's another shuffle inside of a loop. basically this is choosing a different one than the last. you're going to have to change that code to make sure it increments after each one.

Thanks Tony
I appreciate that some contests are like this, but unless you've got lots of images, it is quickly obvious that you are voting a few times on the same image.

Perhaps a future version could have a random or sequential option.

We had found the two shuffles you mention and are currently looking at how to get it to start the array at 0 and work through sequentially to the end of the list.
Which then begs the question : what next? - start again from the beginning, or bring up a "you have voted on all the images" message?
