upload files big images

[alapimba]

Hello

I have a script to upload images, it works fine with small images, like 800x600 and so on. but if i go for 3000x2000 straight from my digital camera i got an error.

Anyone has idea on whats going on?

my errors:

 

Warning: chmod() [function.chmod]: No such file or directory in /home/cocp/public_html/socios_uploadimg.php on line 28

Warning: getimagesize(img/socios/IMG_3607.JPG) [function.getimagesize]: failed to open stream: No such file or directory in /home/cocp/public_html/socios_uploadimg.php on line 29

Warning: Division by zero in /home/cocp/public_html/socios_uploadimg.php on line 30

Warning: imagecreatetruecolor() [function.imagecreatetruecolor]: Invalid image dimensions in /home/cocp/public_html/socios_uploadimg.php on line 39
Problem In Creating image

 

my code:

if ($_FILES['fotos_socios']['name'] == "") {
    echo "escolhe um file";
} else { 
$size = 150; // the thumbnail height
$size2 = 480; // the thumbnail height
$filedir = 'img/socios/'; // the directory for the original image
$thumbdir = 'img/socios/thumb/'; // the directory for the thumbnail image
$prefix = 'thumb_'; // the prefix to be added to the original name
$prefix2 = 'big_'; // the prefix to be added to the original name
$maxfile = '2000000';
$mode = '0666';
$userfile_name = $_FILES['fotos_socios']['name'];
$userfile_tmp = $_FILES['fotos_socios']['tmp_name'];
$userfile_size = $_FILES['fotos_socios']['size'];
$userfile_type = $_FILES['fotos_socios']['type'];
if (isset($_FILES['fotos_socios']['name'])) 
{
$prod_img = $filedir.$userfile_name;
$prod_img_thumb = $thumbdir.$prefix.$id_socio._.$userfile_name;
move_uploaded_file($userfile_tmp, $prod_img);
chmod ($prod_img, octdec($mode));
$sizes = getimagesize($prod_img);
$aspect_ratio = $sizes[0]/$sizes[1]; 
if ($sizes[0] <= $size)
{
$new_width = $sizes[0];
$new_height = $sizes[1];
}else{
$new_height = $size;
$new_width = abs($new_height*$aspect_ratio);
}
$destimg=ImageCreateTrueColor($new_width,$new_height) or die('Problem In Creating image');

The size of the file is probably larger than the upload_max_filesize setting and you are probably getting an upload error - http://www.php.net/manual/en/features.file-upload.errors.php

 

Any upload script must check for upload errors before attempting to use any of the uploaded file information.

 

Also, if you exceed the post_max_size setting, the $_FILES array will be empty, so you must actually check for that condition first, then check the ['error'] element of the $_FILES array for errors.

well i just increased my php.ini settings and it worked.

 

memory_limit = 128M

upload_max_filesize = 10M

post_max_size = 20M

 

 

Theres any bad thing about doing this?

Is there any better way to upload images and faster than this move_upload comand? If i upload images usign picasa it's like 10 times faster then my webforms. whats the reason?
