Yes, the users will have to browser to the image each time they want to upload anything. As far as displaying the images, take a look at http://forums.webdeveloper.com/showthread.php?s=&threadid=15902#post83584

thanks alot for your sincere advice so i modified the code in thsi fashion and when i tried to submit the form then system goes crazy felt like drunk :) the process becomes so slow that it eats uo lot of memories as well as it throw one window by saying you need virtual memory :)


<?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";

?>

To upload the images, take a look at http://forums.webdeveloper.com/showthread.php?s=&threadid=10236&highlight=upload and to modify them to what you need, take a look at http://us4.php.net/gd

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
