I may be misreading your plan, or some of its details, but if I were to
design what I think you are designing, I would not want to put a lot of
images on scrolling backgrounds. I would use a database, like SQLite, and
create a record for each item in your collection of data. If one item of
your data is a set of related image(s), sound recording(s), the name, some
text, or maybe a few different types of texts, then that would be one
database record with a field for each piece of data. One database record per
species, or one per subspecies, or whatever makes sense in your

Once you've established a database and a set of scripts to create a record,
delete a record, edit a record, and retrieve/search for a record, you will
have very little difficulty building your collection and dealing with the
data no matter how few or how many records you put into it.

Instead of scrolling through a dozen images, you will be able to retrieve
and display them in an organized fashion--one at a time, or two at a time,
or whatever, each with its associated sound, text, etc. Once the database is
established, revising the interface will be a breeze because changing your
interface will not involve changing the data. You'll be able to easily
experiment with the presentation of your data, because you will have solved
the principal part--the organization of data.

That's what I would do--but of course I may be missing some crucial points
in your idea.
