[eluser]the_unforgiven[/eluser]
My next question is what do i use to get the thumb stored to the db, currently have:

Code:

$image_data = $this->upload->data();
$data['item_img'] = $image_data['file_name'];

At the end of my model, so now i have a new row in my database called thumb and want to store the thumb ion the database from the thumbs folder.

How does one acheive this?
