Fast - tell me how do you implement a thumbnail loader - well the loading
and storing of the thumbnails that is?
Classically you would likely say something that included individual JPG
files for each thumbnails, and perhaps also something that included
multithreading.
Well that is at least how many application does it, and Linux even have a
standard for it, so applications can share the thumbnails.
I've implemented a much faster way to do it. This is something like 10-100
times faster, and I have code to prove it :-)
