Making thumbnails?

[glenrogers]

OK, so I have this script for uploading images to dir, it also resizes them to max 500px. It to stores a text description and the images pathname in a mysql table.

I want to also make clickable thumbnails of each image(for a gallery)
Can anyone help me out on this?

Heres my code so far

[php]<?php ini_set("memory_limit", "200000000"); // for large images so that we do not get "Allowed memory exhausted"?>

<?php include 'connect.php'; // upload the file if ((isset($_POST["submitted_form"])) && ($_POST["submitted_form"] == "image_upload_form")) { // file needs to be jpg,gif,bmp,x-png and 4 MB max if (($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg" || $_FILES["image_upload_box"]["type"] == "image/gif" || $_FILES["image_upload_box"]["type"] == "image/x-png") && ($_FILES["image_upload_box"]["size"] < 4000000)) { // some settings $max_upload_width = 500; $max_upload_height = 500; // if uploaded image was JPG/JPEG if($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg"){ $image_source = imagecreatefromjpeg($_FILES["image_upload_box"]["tmp_name"]); } // if uploaded image was GIF if($_FILES["image_upload_box"]["type"] == "image/gif"){ $image_source = imagecreatefromgif($_FILES["image_upload_box"]["tmp_name"]); } // BMP doesn't seem to be supported so remove it form above image type test (reject bmps) // if uploaded image was BMP if($_FILES["image_upload_box"]["type"] == "image/bmp"){ $image_source = imagecreatefromwbmp($_FILES["image_upload_box"]["tmp_name"]); } // if uploaded image was PNG if($_FILES["image_upload_box"]["type"] == "image/x-png"){ $image_source = imagecreatefrompng($_FILES["image_upload_box"]["tmp_name"]); } $remote_file = "image_files/".$_FILES["image_upload_box"]["name"]; imagejpeg($image_source,$remote_file,100); chmod($remote_file,0644); //add the files pathname to the database table $uploaded = "image_files/{$_FILES['upload']['name']}"; $aname = $_POST['aname']; $query = mysql_query("INSERT INTO table_images VALUE(NULL, '$uploaded', '$aname')"); // get width and height of original image list($image_width, $image_height) = getimagesize($remote_file); if($image_width>$max_upload_width || $image_height >$max_upload_height){ $proportions = $image_width/$image_height; if($image_width>$image_height){ $new_width = $max_upload_width; $new_height = round($max_upload_width/$proportions); } else{ $new_height = $max_upload_height; $new_width = round($max_upload_height*$proportions); } $new_image = imagecreatetruecolor($new_width , $new_height); $image_source = imagecreatefromjpeg($remote_file); imagecopyresampled($new_image, $image_source, 0, 0, 0, 0, $new_width, $new_height, $image_width, $image_height); imagejpeg($new_image,$remote_file,100); imagedestroy($new_image); } imagedestroy($image_source); header("Location: submit.php?upload_message=image uploaded&upload_message_type=success&show_image=".$_FILES["image_upload_box"]["name"]); exit; } else{ header("Location: submit.php?upload_message=make sure the file is jpg, gif or png and that is smaller than 4MB&upload_message_type=error"); exit; } } ?> Image Upload with resize <!-- body,td,th { font-family: Arial, Helvetica, sans-serif; color: #111111; font-size: 12px; }

Could you use regular html to achieve this?

[php]

<?php if(isset($_REQUEST['show_image']) and $_REQUEST['show_image']!=''){?>

Uploaded Image

<?php }?> [/php]
