The scan rules seem to be case sensitive? Could there 
be a "nocase" option?
Got a huge load of small unwantedpic.JPG because there 
only was a -*.jpg[<10] scan rule...

Perhaps could be circumvented by *.[j,J][p,P][g,G]
[10] ?But a pain in the ass to write, especially if there 
are more filetypes...
