<?

//Get the path to the current directory

$thisname = $z[count($z)-1];
$path = str_replace($thisname, '', $_SERVER['SCRIPT_FILENAME']);

$allowed = array('jpg','gif','png');
//Read through the directory and find all files with proper file extensions

if (($file != '.') && ($file != 'CVS') && ($file != '..')) {
$file_size = filesize($path . $file);
$file_extension = file_ext($file);
if(!is_dir($path . $file) && isset($file_extension) && in_array($file_extension, $allowed)) {
$images[] = array('name' => $file,
'size' => $file_size);
}
}
}
//Check for images present in the directory
$count = count($images);
if ($count < 1){

}elseif ($current_page == $pages){
$back = $current_page - 1;
$pagehtml = '<a class="navi" href="index.php?page=' . $back . '">< Previous Page</a> | <b>Page ' . $current_page . ' of ' . $pages . '</b>';
}else{

$image_nav = '<table width="500px" id="nav"><tr>';
for ($x=$start; $x<=$y; $x++){
if ($x <= $count){
$url = $images[$x -1]['name'];
$image_nav .= '<td align="center" valign="center" width="12.5%"><a href="index.php?page=' . $current_page . '&id=' . $x . '"><img src="' . $url . '" border="0" width="60px"></a></td>';
}
}
$image_nav .= '</tr></table>';
//The image to be shown
$image_view = $_GET['id'];
if (!isset($_GET['id'])){
$image_view = $current_page * 8 - 7;
}
$image = '<img id="view" src="' . $images[$image_view - 1]['name'] . '" width="512px">';
$copy = 'PHP Slideshow v0.1 ©2006 Brian Mahler';
//Display the slideshow
echo '<table id="images" width="500px" border="0" cellpadding="2px">';
echo '<tr><td align="center">' . $pagehtml . '</td></tr><tr><td align="center">' . $image_nav . '</td></tr><tr><td id="pic" align="center" valign="center" style="padding:2px;">' . $image . '</td></tr>';
echo '<tr><td id="copy" align="center">' . $copy . '</td></tr>';
echo '</table>';
//function to get file extension of files
function file_ext($file) {
$extension = split("[.]", $file);
$ext_file = $extension[count($extension)-1];
return strtolower($ext_file);
}
?>
</body>
</html>
ive been trying to study the code yet still no luck.
my goal is:
1. go get the images loaded in their original size -(some of my images have small texts that people cant read em.)
2. get the images sorted by number -(the script displays the images in random order -_-)
anyhelp would be greatly appreciated. oh and im still a newbie in php. so please do give me a good and simple one. Thanks and good day.

Re: [PHP] image gallery problems
I think this line is addressing issue 2 if I understand you correctly
$image = '<img id="view" src="' . $images[$image_view - 1]['name'] . '" width="512px">';
or possibly this one
echo '<table id="images" width="500px" border="0" cellpadding="2px">';
Just try and remove or increase any width.
and as for issue 1 you need to sort the $images array
