Option to auto-rename files to not mess up filename ordering

[GoogleCodeExporter]

For example, when downloading from exhentai, files will have original names 
like 1.jpg...9.jpg, 10.jpg, 100.jpg  
With all naming variables I've tried, the output file will be 
<galleryid>-<filename>.jpg, for example 12345-1.jpg....1235-10.jpg  
This causes issues in both windows ordering and viewer software ordering.  
I tried using the "%width:.6d% " example from the wiki, since the original 
filename is decimal, but it doesn't seem to work.  
For exhentai, the files have a "title" field with the number.  
So I tried the following:  
$rootdir$\pics\%album%\%title:%width:.4d%% (doesn't work at all)  
$rootdir$\pics\%album%\%title[:%width:.4d%]% (starts downloading but endlessly 
starts redownloading same file, so most likely not working)  
$rootdir$\pics\%album%\$fname[:%width:.4d%]$ (same as above)  
Maybe I'm misunderstanding width altogether, and width is the pictures X 
resolution if applicable, in which case it can't be used for renaming files 
anyways.  

In short, I want: 12345-1.jpg to be either 12345-001.jpg or just 001.jpg and 
12345-10.jpg to be 12345-010.jpg or 010.jpg.  
A program similar to yours, domdomsoft manga downloader, has a simple tickbox 
called "rename single digit to three digits" (also applies to 2 digits), 
basically this would be just what I need

Actually I just noticed that the original filenames on exhentai are ordered 
properly.  
It just doesn't seem to get them.   

For example, in this gallery: http://exhentai.org/g/686220/1d1b9db105/  
The files are numbered from 000.jpg to 026.jpg  
If it just downloaded them with these names it would solve everything.  
Graber 1 downloads them correctly with the original names.  
But $fname$ returns 686220-1.jpg for the first file, for example.

Ok, found a solution, even though the original_name field shows up as empty, 
this one actually works.  
So...solved for me, but $fname$ does not pull the original filename from 
exhentai, if that is intended.

haha, yeah, it definitely is misunderstanding.
%width% suppose to meant "picture's width" (%% for picture fields, $$ for other 
variables), and it should be a legit field.
As I got, you trying to make a leading zeroes for "string type" ordering (like 
in windows XP and older or image viewer).
You can use one of this:
$fnn$ - sequence number in current directory;
$nn$ - sequence number in current list;
$fn$ - used to get a sequence number when file is already exist, but order can 
be broken if for some reason "next" picture will be finished before previous.

And example, how to format it: $fnn:.6d$ / $fnn:.6u$. You can add an album 
here: %album_id%-$fnn:.6d$.

$fname$ used to make unique name, not original. exhentai pictures have a 
%original_name% field, but it doesn't guaranties it's unique (even in the same 
album pictures can have the same names).

%original_name% is gathered right during picture's downloading (because 
exhentai's urls to picture are always dynamic, and you can't get it during 
getting list stage).
