Advanced Randomized Image Display Script/Automated to 100 Images

[ridiculous]

So I've been looking around the net trying to find a script that would randomly display MANY images from a file on one's server. MANY in this sense would too many to itemize each image in an array.

I have an Actionscript file that does this just peachy for the flash version of my site, but I'd like to use a PHP script for the non-flash version. Any ideas?


P.S.

I am aware of some scipts already made available here, maybe there is a way to fix them so that a 50+ images can be drawn from a server directory without being itemized:

i.e.


-------------------------------------

Chipmunk Imagerotator
This is all the code for image rotator:

"; } else if($imagevar==2) { print ""; } else if($imagevar==3) { print ""; } else if($imagevar==4) { print ""; } ?>

The rand() function in php, generates a random number, the first passed value is the lower bound, the second is the higher bound. Just paste this code where-ever you want the rotated image and replace the 'URL of image #' with the URL of the image. To adjust the number of images rotated, simply change the $imagevar=rand(1, 4) to $imagevar=rand(1, # of images you want to rotate here) and then for each additional image create an else if case. For example for the fifth image you would want:

else if($imagevar==5)
{
print "";
}

If you want less than 4 images, simply take out the else if cases for that image.

So, since no one else is biting...I'll share my progress.

What I'm thinking is that I should rename all the images in my server directory to a number, (i.e. 1,2,3...n). Then I figure I'll write a script to generate a random number between the first and last numbers I have as filenames and simply inject that number into a print function that prints the image.

I still would like to tweek this so that I don't have to change the script every time I change the number of images in the directory.

Also, I'll have to lookup an image resize script.

I'm not quite sure if i've got what your saying but i think you do, pretty much you want to open a directory, if it's a picture in that directory you want to display it, period, if that's what you mean look at this


[quote]// Open a known directory, and proceed to read its contents
$dir = "/home/blah/public_html/blah/images/;
$picturestring= explode("public_html",$dir);

if (is_dir($dir))
{
  if ($dh = opendir($dir))
  {
        while (($file = readdir($dh)) != false)
  {
 
$testpic= explode(".",$file);
If ($testpic[1] == "png" OR $testpic[1] == "gif" OR $testpic[1] == "jpg")
{

$piclocation = "http://www.yourwebsite.com".$picturestring[1].$file;
[/quote]

hmm that's kinda confusing, i sjut ported that off mywebsite, any questions jsut ask
btw $dir has to be full directory on your server like that one shows
$piclocation is the location of the current pic the directory is reading, so next you'd do whatver you want may
echo "<img src='$piclocation'>":  - to jsut simply display it, or you could laod it into a variable, whatever

is this what you are looking for?

[code]
<?php
function Get_Image($path) {
  $ctr = 0;

  if ( $img_dir = @opendir($path) ) {
      while ( false !== ($img_file = readdir($img_dir)) ) {
        // add checks for other image file types here, if you like
        if ( preg_match("/(\.jpg)$/", $img_file) ) {
            $images[$ctr] = $img_file;
            $ctr++;
        } // end if
      } // end while
      closedir($img_dir);
      $image = $images[array_rand($images)];
      return $image;
  } else {
        return "invalid path";
  } // end else
} // end function

$somepath = 'path/to/images/';
$image = Get_Image($somepath);
?>
[/code]

you could of course modify this to return more than 1 result by changing this:

[code]
$image = $images[array_rand($images)];
[/code]
to this:
[code]
$num = 50; // or however many
for ($x = 0; $x < $num; $x++) {
  $image[] = $images[array_rand($images)];
}
[/code]

and then it would return an array of image names to be used as such:

[code]
// from first example:
echo "<img src = '$somepath/$image'>";

// example if returning array:
echo "<img src = '$somepath/{$image[0]}'>"; // first picture
echo "<img src = '$somepath/{$image[2]}'>"; // third picture

// example of displaying all of them:
foreach ($image as $val) {
  echo "<img src = '$somepath/$val'>";
}
[/code]
