Loading a Random Theme/Image each page load
Ok this might be a kind of hard question to phrase so bare with me. I'm developing a photo gallery site with member levels etc.(www.g-force.net/dev) My question though just involves the header. As you can see on the site I am using a paralex effect header that I got through the vertigo Rocket Theme. This effect utilizes 3 images layers together with mouse sensitive moving.
What I'm trying to achieve is to have a different set of 3 images load every time the page is reloaded. The idea is to create many sets of headers over time using new photos from events and have them added to the pool of randomly selected headers.
I found a piece of code that might work but I'm not too sure if it will. It basically tries to randomise the specified filename it is loading on the page so that if i had header0.png, header1.png and header2.png it would select a random one every page load. As I said I'm not 100% if this could be made to work o if anyone could confirm/deny it would be a great help.
Also if anyone has an alternative method I would love to hear it :)

Your code will work just fine, but it limits you from having flexible image name.
I suggest you to use array to store image set, so that you can define it freely.
Btw, I still use the same randomize logic you're having.
If duplicate random is definitely not allowed then keep this randomize logic.
But if it can tolerate duplicate random sometimes then only this line is enough for the whole code from line 11 through line 37
$num = rand(0, $maxKey);

Ive got that code inside the <head> tags of the template index.php file
Do I need to specify the folder structure for my array images?
Can you spot what I've got wrong?

It didn't work because $aryImgPool has no sub array with neither key 'header' nor 'middle' in it
Just add 'header' & 'middle' to $aryImgPool or change the keys in these lines

Ok that was a stupid mistake on my part. Fixed up that error, and a pathing error (folder structure is templates/template_name/im ages/theme 5/filename )

From what I can tell the randomise feature is working (different numbered files in the page source each refresh) and the file it is trying to pull (templates/rt_vertigo_j15/ images/the me5/5showc ase-layer3 .png) goes to the image it should be.
So its probably one last little thing ive missed....

EDIT: Ok, i know where the problem is now I just don't know what to do about it. I renamed the original images the header was trying to pull which is why nothing was coming up. With the original images in the folder the header displays as it did before i started. With no randomizing.
So the problem lies in this code actually taking over the headers images...
