Hello,
I’m currently creating a website where my members can create a photo album and upload their photos. I’ve tested my php script and the script is taking too long to upload an image. Is there a way to speed up the upload process?
Could you please post the code you currently have.
<?php
// no files uploaded
if (count(array_unique($_FILES['image']['error'])) == 1 and $_FILES['image']['error'][0] == 4)

else {
for ($i=0; $i<$max_uploadnr; $i++)
{
$thumbwidth = 125;
$thumbheight = 125;
// file not uploaded
if ($_FILES['image']['error'][$i] == 4) {/* do nothing here */}
// file exceeds filesize
elseif ($_FILES['image']['error'][$i] == 1 or $_FILES['image']['error'][$i] == 2)
{
Error("<b>".$_FILES['image']['name'][$i]."</b>: the file exceeds the filesize limit!<p>");
}
// files partially uploaded
elseif ($_FILES['image']['error'][$i] == 3)
{
Error("<b>".$_FILES['image']['name'][$i]."</b>: the file was partially uploaded!<p>");
}
// temporary folder missing
