Req:Adding Filename at top of image display

[sbpoole]

I would like to be able to add the filename right beside of PICTURE x/xxx on the image display page.  I sale prints on my website and sometimes customers provide me with the current image position instead of the filename.  Example, someone wants to order picture 44, where I need the filename DSC_2859.  They got the 44 from the top of the display where you have the slideshow, Picture 44/1428, ecard, etc.  

This is what I would like if anyone can help.

   Picture 44/1428  Filename-->DSC_2859

I messed around with it but I couldn't call up the filename.  Thanks, Sonny
