Hi all,
I would like to submit a patch to GQview that I find extremely useful.

I oftern use GQview to rename pictures taken with digital cameras with the 
"multiple rename": I modified it in this way:
- auto select the "auto rename" function
- propose the "end text" according to the filename extension
- calculate automatically the start# and padding by searching how many 
pictures already start with the "begin text"

It made it to work in this way. If I have 5 pictures like this:
1.jpg
2.jpg
3.jpg
4.jpg
5.jpg

Then I rename:
1.jpg -> davide1.jpg
2.jpg -> davide2.jpg
3.jpg -> xxx.jpg

When I select 4.jpg and 5.jpg for multiple rename and type "davide" as begin 
text, it will automatically propose "3" as start#.

I used a simple call to "find -regex | wc -l" to count the number of existing 
files with the same pattern.

Hope someone will find this useful...

Bye
Davide
