if you have all images in one directory and ONLY images in that folder
you can try something like this:
$path = '/path/to/directory/with/images';
$handle = opendir($path);
while (false != ($file = readdir($handle)))
{
if ($file != "." && $file != ".." && !ereg('.php', $file))
#excluding . and .. files and php file with this code
{
$images[] = $file;
}
}
closedir($handle);
$last = count($images);
foreach($images as $key => $value)
{
swtich($key)
{
case (0):
echo '[ next ]';
break;
case ($last):
echo '[ prevous ]';
break;
default:
echo '[ previous ] [ next ]';
break;
}
}
I hope this will help
;)

I have a client that maintains picture galleries by simply dropping
images into a directory. I have a template created that when loaded,
with a specific $ID, will load the image that corresponds to that
$ID. The request now is to have previous and next buttons that web
surfers can click on to cycle through the rest of the images in the
directory (instead of having to close that pop-up and click on another
image to look at.)
What's the best way to go about this? Since I don't have a list of
images in any kind of array (such as a result from DB query), I'm a
bit at a loss here. Obviously if someone clicks on the first image on
the gallery page, it should only have a 'next' button, and if they
click the last image, it should only have a 'previous' button, but
anything else on the page should have a 'previous' and 'next' button.
I just don't know how to keep that relationship or how to start coding
that.
Ideas/suggestions/pointers are much appreciated here.
