I got the idea from www.cosforums when the banner changes every new page

Code:

<?
# Put the SERVER PATH to image directory.
# INCLUDE trailing slash
$dir = "/home/deathqe/public_html/forum/randphotos/";
# Put the HTML PATH to image directory.
# DO NOT include trailing slash
$html_dir = "http://www.death-eater.net/forum/randphotos";
$dir_handle = opendir($dir);
$image_array = array();
# This opens up the image directory, grabs all files with a ".jpg" extension
# and puts them into an array. You can set whatever extension you'd like here.
# Just switch out the .jpg for .gif, etc. If you have more than one extension,
# replace this line with something like this:
# if (($file !=".") && ($file !="..") && (substr($file, -4) == ".jpg") || (substr($file, -4) == ".gif"))) {
# This will pull up all .jpg OR .gifs. If you name all the images you want to pull
# a certain way (example, image-thumb.jpg or image.thumb.jpg) you can do this:
# if (($file !=".") && ($file !="..") && (substr($file, -10) == ".thumb.jpg")) {
# basically you want to put the extension in quotes and then count how many characters
# it is and place that after $file, -
while ($file = readdir($dir_handle)) {
if (($file !=".") && ($file !="..") && (substr($file, -4) == ".jpg")) {
$file_name = "$html_dir/$file";
$image_array[$file_name] = $file_name;
}
}
# sorts the array. For some reason this won't work at all
# unless this is done. Can anyone tell me why?
sort($image_array);
$count = sizeof($image_array);
# trims all the URLs of whitespace and assigns each
# item in the array a number to identify it.
for($i = 0;$i<sizeof($image_array); $i++) {
$image[$j++] = rtrim($image_array[$i]);
}
# assign a random value
$r = rand(0,$count-1);
# get the size of a random image
$size = getimagesize($image[$r]);
$width = $size[0];
$height = $size[1];
$img_src = "<img src=\"$image[$r]\" width=\"$width\" height=\"$height\" alt=\"This is a Random Image\" />";

closedir ($dir_handle);
?>
<html>

<head>
</head>

<body>

<p align="center">
<? echo '$img_src; ?><img border="0" src="file:///C:/Documents%20and%20Settings/Owner/Desktop/banner.gif" width="385" height="140"></p>

</body>

</html>

But I keep getting a parse error , i dont undertand when i wrote the code and tested on my machine server it was fine

Glad you could get it!
I'd recommend formatting your statements so it's easier to read... see my next post.

I would do this:

Code:

<?
# Put the SERVER PATH to image directory.
# INCLUDE trailing slash
$dir = "/home/deathqe/public_html/forum/randphotos/";
# Put the HTML PATH to image directory.
# DO NOT include trailing slash
$html_dir = "http://www.death-eater.net/forum/randphotos";
$dir_handle = opendir($dir);
$image_array = array();
# This opens up the image directory, grabs all files with a ".jpg" extension
# and puts them into an array. You can set whatever extension you'd like here.
# Just switch out the .jpg for .gif, etc. If you have more than one extension,
# replace this line with something like this:
# if (($file !=".") && ($file !="..") && (substr($file, -4) == ".jpg") || (substr($file, -4) == ".gif")))
# {
# // This will pull up all .jpg OR .gifs. If you name all the images you want to pull
# // a certain way (example, image-thumb.jpg or image.thumb.jpg) you can do this:
# if (($file !=".") && ($file !="..") && (substr($file, -10) == ".thumb.jpg"))
# {
# // basically you want to put the extension in quotes and then count how many characters
# // it is and place that after $file, -
while ($file = readdir($dir_handle))
{
if (($file !=".") && ($file !="..") && (substr($file, -4) == ".jpg"))
{
$file_name = "$html_dir/$file";
$image_array[$file_name] = $file_name;
}
}

# sorts the array. For some reason this won't work at all
# unless this is done. Can anyone tell me why?

sort($image_array);
$count = sizeof($image_array);

# trims all the URLs of whitespace and assigns each
# item in the array a number to identify it.

for($i = 0;$i<sizeof($image_array); $i++)
{
$image[$j++] = rtrim($image_array[$i]);
}

# assign a random value
$r = rand(0,$count-1);

# get the size of a random image
$size = getimagesize($image[$r]);
$width = $size[0];
$height = $size[1];
$img_src = "<img src=\"$image[$r]\" width=\"$width\" height=\"$height\" alt=\"This is a Random Image\" />";

closedir ($dir_handle);
?>
<html>

<head>
</head>

<body>

<p align="center">
<? echo '$img_src'; ?><img border="0" src="file:///C:/Documents%20and%20Settings/Owner/Desktop/banner.gif" width="385" height="140"></p>

</body>

</html>

... Note the for loop and the while statement, etc.

I just think it's more organized and easier to read that way...

I recommed you to get a PHPEditor, that helps a lot

It is like VS.NET or FrontPage...

Try Googling for a PHPEditor, that will fix your little details when programming...

I have made several scripts that didn't work at first for the stupid errors like missing a letter or a ";" or the " in self...

Hahahah programming is so perfectly design for mistakes....

Let me know about the editor Razz

See ya

If you have a MySQL database, you can also insert your pictures (or only their names) into, and after use the rand() function to select one random image on every new page.

Code:

SELECT pic_id FROM pictures ORDER BY rand()
