Need Help on a php image gallery

1bigbear · November 28, 2007

I use the Micro Photo Gallery the script finds all .jpg files and creates thumbnails if there isn't one and links the thumbnail with the jpg file.

I will use this script on a site, and I don't want to upload the same gallery on the other site, I just want the script to read from the folder of my first site the files. The original script only reads from the folder that is in.

Here is the script:

^<?php

^{/*************************************************}

^{* Micro Photo Gallery}

^*

^{* Version: 1.0}

^{* Date: 2007-04-05}

^*

^{* Usage:}

^{* Just copy these files into your image folder}

^*

^{****************************************************/}

^{$columns = 5;}

^{$thmb_width = 120;}

^{$thmb_height = 80;}

^{function resizeImage($originalImage,$toWidth,$toHeight){}

^{// Get the original geometry and calculate scales}

^{list($width, $height) = getimagesize($originalImage);}

^{$xscale=$width/$toWidth;}

^{$yscale=$height/$toHeight;}

^{// Recalculate new size with default ratio}

^{if ($yscale>$xscale){}

^{$new_width = round($width * (1/$yscale));}

^{$new_height = round($height * (1/$yscale));}

^}

^{else {}

^{$new_width = round($width * (1/$xscale));}

^{$new_height = round($height * (1/$xscale));}

^}

^{// Resize the original image}

^{$imageResized = imagecreatetruecolor($new_width, $new_height);}

^{$imageTmp = imagecreatefromjpeg ($originalImage);}

^{imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0, $new_width, $new_height, $width, $height);}

^{return $imageResized;}

^}

^{function generateThumbnails(){}

^{global $thmb_width,$thmb_height;}

^{// Open the actual directory}

^{if ($handle = opendir(".")) {}

^{// Read all file from the actual directory}

^{while ($file = readdir($handle)) {}

^{// Check whether tha actual item is a valid file}

^{if (is_file($file)){}

^{// Check whether the actual image is a thumbnail}

^{if (strpos($file,'_th.jpg')){}

^{$isThumb = true;}

^{} else {}

^{$isThumb = false;}

^}

^{if (!$isThumb) {}

^{// Process the file string}

^{$dirName = substr($file,0,strpos($file,basename($file)));}

^{if (strlen($dirName) < 1) $dirName = '.';}

^{$fileName = basename($file);}

^{$fileMain = substr($fileName,0,strrpos($fileName,'.'));}

^{$extName = substr($fileName,strrpos($fileName,'.'),}

^{strlen($fileName)-strrpos($fileName,'.'));}

^{// Check if the actual file is a jpeg image}

^{if (($extName == '.jpg') || ($extName == '.jpeg')){}

^{$thmbFile = $dirName.'/'.$fileMain.'_th.jpg';}

^{// If a thumbnail dosn't exists tahn create a new one}

^{if (!file_exists($thmbFile)){}

^{imagejpeg(resizeImage($file,$thmb_width,$thmb_height),$thmbFile,80);}

^}

^{function getNormalImage($file){}

^{$base = substr($file,0,strrpos($file,'_th.jpg'));}

^{if (file_exists($base.'.jpg')) return $base.'.jpg';}

^{elseif (file_exists($base.'.jpeg')) return $base.'.jpeg';}

^{else return "";}

^}

^{function displayPhotos(){}

^{global $columns;}

^{generateThumbnails();}

^{$act = 0;}

^{// Open the actual directory}

^{if ($handle = opendir(".")) {}

^{// Read all file from the actual directory}

^{while ($file = readdir($handle)) {}

^{// Check whether tha actual item is a valid file}

^{if (is_file($file)){}

^{// Check whether the actual image is a thumbnail}

^{if (strpos($file,'_th.jpg')){}

^++$act;

^{if ($act > $columns) {}

^{echo '</tr><tr><td class="photo"><a href="'.getNormalImage($file).'"><img src="'.$file.'" alt="'.$file.'"/></a></td>';}

^{$act = 1;}

^{} else {}

^{echo '<td class="photo"><a href="'.getNormalImage($file).'"><img src="'.$file.'" alt="'.$file.'"/></a></td>';}
