Also I forgot to ask, how the other CMS system deal with generating the thumbnails? I mean about Wordpress, Drupal, Joomla, etc.
Do they store predefined sizes or generate them on the fly?
I guess their logic should be the best, or maybe not, but I want to implement something smart in my CodeIgniter CMS.
I didn't mention, but I think it's not important to this, I use Grocery CRUD for the admin panel.
