Gallery with Subtitles & breaks - Posible?

[cits_4_pets]

Putting breaks-subtitles in gallery page is this posible.
I have a gallery, Windows, (http://www.pbase.com/cits_4_pets/looking_out) that I would like to put in divisions with subtitles so as to keep a series of photos together.
an example...3 photos of one subject..."Garage Door", break with subtitle "At The Old Cattle Ranch," with maybe 8 or 9 images, another break and title 'The Skylights' with 5 images, another break and subtittle, The Arch Top Window etc.
As it is I put in some 'extra' photos so that I could keep a series in the same row.

Thank you! I am relatively new to html & all that I have learned is from my short time on Pbase!
