substring for html export watermarks?

[ron_hiner]

I'd like to put on my watermarks a portion of my filename... but not the whole thing...

Is there a way to do that? 
For example: If my file name is.... "the_hannah_montana_concert_where_i_sat_in_the_first_row_322.jpg"
I want my watermark to say simply  "Image #322"

syntax something like this:
Image #{those_last_three_chars of{filenamebase}}

Is there a way to do that?  (I can't find anything relevant when I search for the word substring)

Thanks!

As long as you have PM 4.5.2 or higher you can do this:

Image #{filename:-3}

That should do what you want.
