Random images?

[Corybu]

Anyone know how to display random images?

Ive got a website that I need to make for a friends band, and I have various logos that i'd like to place in a frame in the top left corner.

If anyone could tell me how this os done, or point me to t autorial for it, or give me a code/script for it, Id be very grateful.

Thanking you all in advance,

Cory.

well... you'd have to use some sort of scripting language... ie: perl, php etc.

[Corybu]

I dont know either of those....

Could you or someone here help me out with this one?

I was hoping there was an html way...

[Blade]

no... html is pretty much tags that format text, it cant caculate anything
well... i'd read the images from a folder into an array, then use a random integer in the array element from 1 to the amount of pictures in the array, then use html to present it...

[Corybu]

Lol... I dont get it. Do all that stuff with html? or another script?

Ive never done any scripting...

PHP:

code:

function getRandomImage($dir,$type="random") { global $errors,$seed;   if (is_dir($dir)) {    $fd = opendir($dir);    $images = array();       while (($part = @readdir($fd)) == true) {            if ( eregi("(gif|jpg|png|jpeg|bmp)$",$part) ) {               $images[] = $part;           }       }     // adding this in case you want to return the image array     if ($type == 'all') return $images;     if ($seed !== true) {       mt_srand ((double) microtime() * 1000000);       $seed = true;     }             $key = mt_rand (0,sizeof($images)-1);     return $dir . $images[$key];   } else {       $errors[] = $dir.' is not a directory';       return false;   } }

So, with that, I just put it on the html page where I want it to appear, and put the pics in a directory all by themselves?

[Amailer]

Which one you are talking about?

[Corybu]

the php script

[Amailer]

1: you need php installed,
create a .php file (i.e: randomeimg.php )
put the script in, and add afer that

code:

$dir="./where the/images/are/"; getRandomImage($dir);

[Blade]

code:

<? $dir = "images/"; $i = 0; if ($handle = opendir($dir)) {   while (false !==($file[$i] = readdir($handle))){     $i++;   } } $img = $dir . $file[rand(2,$i - 1)]; echo "<img src=$img>"; ?>

what amailer gave you as a function... this is the most simple way you can do it...

its php... you need a server that supports php to use it, and you also need ot name your file .php instead of .htm/.html ... or else the server wont execute it..

you can see it working at http://dblade.sytes.net/new/readdir.php

what it does is it reads the folder /images (which is in my new folder on the server) that is full of images, into an array.. then it gets a random number between 2 (because the first two it reads is . and .. ) and the maximum number of images in the folder, then you use the random number in the array to call a random array element
ie: $arrayname[randomnumber]

Im assuming I need some kind of software installed to run PHP then?

This site isnt getting hosted on a private server... its just going on free webhosting... Ill have to see if it can use php...

[Blade]

umm... the server you're using needs to have php for you to use php...
theres only a couple free server that i know of that have php...
tripod.co.uk and host.sk (which isnt in english)

[Corybu]

I see... Well, as long as its free, I can probably have the site hosted there... Ill just get redirect service for it.

Thanks for the help guys.

better if you use the JAVASCRIPT ONE, cuz you don't have PHP
