Random Image without Table?

slevytam

Hello,

Is there a way to display a random image without using a table?

I have a directory full of images and I would just like to display in my page without having to make a table etc.

Thanks,

$totalimages = 10; // number of images to be used

srand();
$rand = rand(0,$totalimages);

echo "<img src=\"image/$rand.gif\">";

Name your images using just numbers..

1.gif
2.gif
etc..

However, if your image names are not in consecutive number format (or in a number format at all), you'll have to loop through every file, add the name to an array, then pick a random key from the array.

<?php
$dir = opendir("./images/");
while ($file = readdir($dir)) {
  $filearray[] = $file;
}
closedir($dir);
$randnum = rand(0,count($filearray));
echo("<img src=\"".$filearray[$randnum]."\">");
?>

And there you have it. Most everything is self-explanatory.

you need to add srand() to that or it will show the same image everytime the page loads, unless you refresh

This is only true on onlder versions of PHP. You don't have to seed a random any more.
