Random Image Selection
July 25th, 2008
This is a neat little trick I sometimes use to freshen up websites that suffer from heavy text content The script will use an array of predefined images that exist in a directory and choose at random one of the images from within it.
// PHP Random Image Selecter
$arr_img_list = array('1.jpg','2.jpg','3.jpg','4.jpg','5.jpg','6.jpg','7.jpg','8.jpg','9.jpg');
$i_lower_limit = 0;
if(count($arr_img_list)>0){
$i_upper_limit = count($arr_img_list)-1;
}else{
$i_upper_limit = 0;
}
$i_random_no = mt_rand($i_lower_limit, $i_upper_limit);
$str_chosen_image = $arr_img_list[$i_random_no];
<img src=”/random/” class=”border” alt=”a random picture” />
Warning: The script as such simply displays the images in their natural format so its your responsibility to size them before dropping them in place. One good enhancement I will consider for the future would be to to add a thumbnail generating script to handle any size images.
