This tutorial will explain how to upload files:
www.phpbuilder.com

To maintain a numbering for each thumbnail, you'll have to store info about each image somehow. A text file or a database will do nicely, and you can then store a text comment about each thumbnail as you wish.

thanks garth for your sincere advice ,well i tried to do something like this i m having all images stored in folder let say ../asset/upload
so when im trying to upload then system process become so slow and its very time taking to get image
could you please let me know in which line the error is

PHP Code:


<?PHP

$folder = "../assets/upload/";
$handle = opendir($folder);

# Making an array containing the files in the current directory:
while ($file = readdir($handle))
{
    $files[] = $file;
}
closedir($handle);

#loop through the files, and only take files that are images.
foreach ($files as $file) {
    $f_name = $file;
    $fileextention = split ('[.]', $f_name);
    $fileext = $fileextention[count($fileextention)-1];
    if($fileext=="gif" or $fileext=="png" or $fileext=="bmp" or $fileext=="jpg" or $fileext=="jpeg" or $fileext=="jpe" or $fileext=="tif" or $fileext=="tiff") {
        $filename[] = $file;
    }
}
#echo out the images...
echo "<table style=\"width: 100%;\">\n\t
\t<tr>\n\t\t<td>Images</td>";

for ($i = 0; $i < count($filename); $i++) {
    if ($i % 3 == 0) {
        echo "\n\t</tr>\n\t<tr>\n";
    }
    echo "\t\t<td style=\"width: 33%; border: gray 1px solid; padding: 3px;\"><img src=\"".$folder.$filename[$i]."\" alt=\"Gallery Image\"\"></img><td>\n";
}
echo"\n\t</tr>
</table>\n";

?>






<table border="0" width="500" cellspacing="0" cellpadding="0">
    <form action="<?=$HTTP_SERVER_VARS['PHP_SELF'];?>"  method="post" enctype="multipart/form-data">
        <tr>
            <td width="130" height="20" align="left" valign="top"><font color="#000000" face="verdana" size="1">Image To Upload :</font><br></td>
            <td width="370" height="40" align="left" valign="top"><input type="file" size="40" name="file"></td>
        </tr>
        <tr>
            <td colspan="2" height="20" width="500" align="center" valign="top"><input type="submit" name="upload" value="Upload"></td>
        </tr>
    </form>
</table>

I can't see offhand why the script is slowing down yor PC/server. File system functions do slow things down a little, but you shouldn't notice it that much.

How big are the images that are being uploaded. If you're uploading 5mb images over a 56k modem, it will be slow, and the server will slow down, waiting and waiting...

Try sticking in some timing code,to see what is taking time.www.desilva.biz

You can resize images to exact numbers using the GD library, but it's tough to learn. Have a look at this script off Hotscripts.com:

thanks alot but i tried to upload image from (../assets/upload)which is 3.4kb size but still the system becoms too slow
and may be im using PHP version 4.0.6 which i dont have rights to update and GD librarries :------
GD Support enabled
GD Version 1.2

hope you have any clue for this

zuzupus · #6 27-Aug-2003, 07:12

sorry Pyro for late reply as im using older version of PHP 4.0.6
as i dont ahve any rights to update it moreover its on remote server and GD library:------- GD Support enabled and
GD Version 1.2

i can explain you once again whats the problem actually there is path in server ../assets/upload and here everyday all thumbnails is stored and clients have rights to upload all these thumbnails to his machine for that when he uplaod and submit the form he can see thumbnails and when i try below code it works for all functions like it checks whether file is more and file exits or not but never tells that it uploaded sucessfully,but i will be very glad if you modify htis code so that it can print all thumbnails in order from altest to older thumbnails

PHP Code:


<?php
                  $maxsize = "16384";
                  $maxwidth = "200";

          if(isset($HTTP_POST_VARS['upload'])){
           if (!empty($HTTP_POST_FILES['file']['name'])){
             $nama=$HTTP_POST_FILES['file']['tmp_name'];
             $allowed = array(".jpg"=>"2",".jpeg"=>"2");
             $size = getImageSize($nama);
             $imgtype = $size[2];
  if(!in_array($imgtype,$allowed)) {
     echo "<font face=\"verdana\" size=\"2\" color=\"#000000\"><b>Sorry! File Format Not Allowed!</b></font><br>";
                exit();
                         }
        $files = $HTTP_POST_FILES['file']['size'];
                    if($files > $maxsize){
                  echo "<font face=\"verdana\" size=\"1\" color=\"#000000\">Exceeded maximum file size</font><br>\n";
                echo "<font face=\"verdana\" size=\"1\" color=\"#000000\">Maximum File Size is ". round(($maxsize/1024), 2) . "kb</font><br>\n";
              echo "<font face=\"verdana\" size=\"1\" color=\"#000000\">Your File Size is ". round(($files/1024), 2) . "kb</font><br><br>\n";
                exit();
                }
      $fol = "../assets/upload/".$HTTP_POST_FILES['file']['name'];
        echo $fol;
            if(file_exists($fol)) {
                  die ("<font face=\"verdana\" size=\"1\" color=\"#000000\">File name exist !!</font>");
                         }

                   else {
       copy($_FILES['file']['tmp_name'], "../assets/upload/" . $HTTP_POST_FILES['file']['name']);
         unlink($HTTP_POST_FILES['file']['tmp_name']);
               $oripic= "upload/".$_FILES['file']['name'];
               $size = getImageSize($oripic);

               $ratio = $imgwidth / $imgheight;
               $nratio = $maxwidth / $ratio;
               $newheight = $nratio;
               if($imgwidth > $maxwidth){
                     $quality = 85;
             $thumb = ImageCreateTrueColor ($maxwidth, $newheight);

              imagedestroy($thumb);
             }
       echo "<font face=\"verdana\" size=\"2\" color=\"#000000\"><b>File Uploaded Successfully</b></font><br><br>";
                          }
                     }
                    else {
