Hey. I have 2 problems with thumbnails. Hope you could help to solve at least one of them 1.I have made a form on my website where the user can upload image and add some extra information. So I made thumbnails for uploaded images that are stored in folder (they're stored in the database as well, but these thumbnails are linked with the folder not database) and when I click on the thumbnail I want it to show the big image and some data from database that was added when the user uploaded the image (like- name and date). Now when I click on a thumbnail it shows me all the data that's in the database- including other images as well. How to link a thumbnail that is made in folder with data from database? (thumbnails and original images have exact the same name). 2. I used this script to create thumbnails, but it is only for .jpg images. What should I add to allow .png , .jpeg and .gif extensions as well? /** settings **/ $images_dir = 'images/'; $thumbs_dir = 'images_thumbs/'; $thumbs_width = 200; $images_per_row = 3; /* function: generates thumbnail */ function make_thumb($src,$dest,$desired_width) { /* read the source image */ $source_image = imagecreatefromjpeg($src); $width = imagesx($source_image); $height = imagesy($source_image); /* find the "desired height" of this thumbnail, relative to the desired width */ $desired_height = floor($height*($desired_width/$width)); /* create a new, "virtual" image */ $virtual_image = imagecreatetruecolor($desired_width,$desired_height); /* copy source image at a resized size */ imagecopyresized($virtual_image,$source_image,0,0,0,0,$desired_width,$desired_height,$width,$height); /* create the physical thumbnail image to its destination */ } /* function: returns files from dir */ function get_files($images_dir,$exts = array('jpg')) { $files = array(); if($handle = opendir($images_dir)) { while(false !== ($file = readdir($handle))) { $extension = strtolower(get_file_extension($file)); if($extension && in_array($extension,$exts)) { $files[] = $file; } } closedir($handle); } return $files; } /* function: returns a file's extension */ function get_file_extension($file_name) { return substr(strrchr($file_name,'.'),1); } /** generate photo gallery **/ $image_files = get_files($images_dir); if(count($image_files)) { $index = 0; foreach($image_files as $index=>$file) { $index++; $thumbnail_image = $thumbs_dir.$file; if(!file_exists($thumbnail_image)) { $extension = get_file_extension($thumbnail_image); if($extension) { make_thumb($images_dir.$file,$thumbnail_image,$thumbs_width); } } echo '<a href="',$images_dir.$file,'"><img src="',$thumbnail_image,'" /></a>'; } } else { echo '<p>There are no images in this gallery.</p>'; } Really waiting for some answers. Thanks!!!
