I'm using the Image Manipulation Library to resize user uploaded images which is then input into a database called images, to give you a quick outline on how its setup:
Code: CREATE TABLE IF NOT EXISTS `images` (
`id` int(20) NOT NULL AUTO_INCREMENT,
`alias` varchar(40) NOT NULL,
`file_location` text NOT NULL,
`original_width` int(11) NOT NULL,
`original_height` int(11) NOT NULL,
`resized_versions` text NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=4 ;
The alias is the ORIGINAL file name when uploaded, the resized_versions is a json array of resized image values for example:
Code: {"75_75":{"width":75,"height":75,"file_location":"GBPIMtcC4PjlsTXK.JPG"},"60_60":{"width":60,"height":60,"file_location":"iPKKYSDtFMcC48oQ.JPG"}}
75_75 = width_height
okay, now you know how the database is working this is how I'm using the Image Manipulation library...
For example when I call the function and this can be called anywhere in a page between 1 and 50 times...
Code: $this->mimage->display_image('no-image', 75, 75, 'image', array
('title' => 'no image available'));
// This is just an example, and its not always no-image called...
The code for MImage model:

I can load the page the first time (empty rezized_images array in the database column) and it'll resize one image, then the rest of the images on the page will resize and get a random name generated, but it doesn't upload? :S refresh the page and then the next image works okay but the rest aren't, basically every time I refresh, the next image appears... but I get a tonne of errors.
I keep getting two errors messages, the one at the top of the post quoted, and my custom one...

It's been driving me crazy for hours, if anyone can shed any light I'd more than appreciate it!

Try this:
Code: $result =NULL; // default
// run the resize script and get the result
if (!$this->image_lib->resize())
{
// if there are errors print them out for testing purposes
print $this->image_lib->display_errors();
}
else
{
// if its uploaded and manipulated okay then we add it into the database
if (file_exists($config['new_image']))
{
$this->db->where('alias', $alias)->update('images', array('resized_versions' =>
json_encode(array_merge($resized_images, $resized_array))));
# NEW POSITION
$this->image_lib->clear();
unset($config);
# Maybe best to only have one return value
$result = base_url('uploads/images/' . $new_image_rand);
# return base_url('uploads/images/' . $new_image_rand);
}
else
{
print 'Error in image manipulation';
}
}
# MOVED to NEW POSITION because not called if (file_exists(...))
# $this->image_lib->clear();
# unset($config);
return $result;
}

Thank you for your reply John, unfortunately that didn't seem to fix the problem, and I'm getting the following error about 21 times whilst loading 7 images, but its still only doing the first image each time on the page... :\
Quote:Your server does not support the GD function required to process this type of image.
This errors obviously a lie because it's already done one image on that page *sigh*
Here's the updated source code of mimage model:

} elseif ($get_image->num_rows() == 0 || !file_exists($this->upload_prefix . $this->upload_dir . $img->file_location)) {

// Just keep using the alias variable
$alias = $this->default_alias;
$get_n_image = $this->db->select('id, alias, file_location, original_height, original_width, resized_versions')->

Other information, I'm using the 2.1.0 version of CI, I'm just in the process of updating Image_lib to the latest version on Github, sorry for bump, not enough space on the last post to add.
[eluser]John_Betong_002[/eluser]
It could be a memory problem. What size are your images. Maybe check for the available memory.
Have you checked phpinfo() to see the name of the GD Library?
Vague memories that I had a similar problem a long time ago and after creating the thumb-nail I put a sleep()/delay() for about a tenth of a second and it seemed to cure the problem.
If you send the image links I will try and create thumbnails using your code.
Time for my beauty sleep...

The images are the sensibly named ones, any generated are the random strings.

Hi Bondie,
You will *NOT* be delighted to know that I downloaded your images and created a brand new controller to pick the images from the path and to create thumbnails. Unfortunately I had exactly the same problem of only creating a single thumbnail and also generating errors.
The path to the solution:
I reverted back to using a "MarcoMonteiro THUMB Helper" and it worked every time???
http://ellislab.com/forums/viewthread/204185/
I spotted the difference between the helper and both your code and mine. The following missing line makes all the difference - don't you love computers 
Code: $this->load->library('image_lib', $config);
$this->image_lib->initialize( $config ); // MISSING LINE
Try inserting the line and if it solves your problem then please create a Debug Report Error and hopefully mark this thread as [SOLVED]
[eluser]Bondie[/eluser]
Spot on pal!
Thank you for the help, much appreciated!
[eluser]CroNiX[/eluser]
Yes, there is a bug in the image library and it wont load with the config. You have to set (initialize) the config manually.
