thumb gererating problem

[eluser]Bigil Michael[/eluser]
hi friends.
I have configured codeigniter 2.1.0 and uploaded image using upload library. my problem is in thumb generation
in ci 1.7.1 thumb marker is

Code:

$config1['thumb_marker'] = 'thumb_';

thumb image name will be thumb_imagename.jpg

in ci 2.1.0 thumb marker is

Code:

$config1['thumb_marker'] = 'thumb_';

now thumb image name like this imagename_thumb.jpg

it will make too difficult to display thumb image, because in my db image name is like this
imagename.jpg.

so i want to use this code

$config1['thumb_marker'] = 'thumb_';

can anyone help me???? where i have to change the code to generate thumb like 'thumb_imagename.jpg'.
thanks in advance....

What I do is: I store the image name without the extension, then in another db field I store the extension. Then I can easily call the thumb since you have the image name and the image extension separated.

I'm curious: why do you need this format?
Its not secure save your images with their raw names.
Encrypt your names like md5(time().$imagename) or anything else.
When you upload your image (physic), save the image with the same name.
If the upload is ok, save this image in your database.
Other tip: use rezise for crate your thumbnail or use any helper to generate a dynamic output.

If you need some code, i can code it. Lemme know!

First,
read the guide: http://ellislab.com/codeigniter/user-gui...e_lib.html

After this, try out this (check syntax errors, please):

Code:

$config['image_library'] = gd2;
$config['source_image'] = $path.$file;
$config['new_image']     = $path.$newfile;
$config['width']        = 100;
$config['height']       = 100;

$this->image_lib->initialize($config);

if ( ! $this->image_lib->resize())
{
    echo $this->image_lib->display_errors();
} else {
    echo 'Image uploaded!';
}

I made a thumb helper a while ago. You can check it out if you want.
