Need help on coding a script that selects and displays a random image?

Hi guys.

I'm a keen photographer and have hundreds of good photos.

I want to build a very simple site that will just have my logo at the top a little bit of text then I want a picture.

Here's the tricky part. I want to upload my hundreds of photos onto my server then I want a script that will select on of those pictures at random then display that image on the homepage.

So each time the user refreshes it will pick a completely random picture again.

Please could someone tell me the code for how to do this!

Many Thanks

 

Put all the images in a folder.
Save this as randomImage.php and place in the same folder as images.
On site, <img src="folder-of-images/randomImage.php" alt="" />

This is probably the simplest way, if you don't want to name each image a number then use rand().'.jpg'; or whatever.

 

Hi, I'm using jQuery,
I do a div where I display images within as background images
I give my images names ending with numbers from 0 to x-amount of pics
and use something like this to generate random image within that div:
(with a bit of fading in effect)

  $(document).ready(function(){
var totalNum = 5; //the total number of images in a folder.
 var rndNum = Math.floor(Math.random() * totalNum);
 $("div#loader").hide(10)
 $("div#loader").css("background-image","url(_images/dental_implants" + rndNum  + ".jpg)");
 $("div#loader").fadeIn(1500);
  });
