You have to ask yourself, just how much does security matter? It''s obviously preferable to write the data into a separate file so that you don''t have to recompile every time you want to change it, so that''s one big plus for external resources. The thing is, if someone ever really wanted to see/use/edit this data, it would be a breeze even if it were compiled into the source if you don''t use any encryption.

My verdict: don''t bother.
