suppose for a game like chess, the code containing the logic of chess must be one separate program(elf) and the images of chessboard and the pieces must have been kept in separate directory which are used by elf at runtime.

with respect to linux am i correct?

if yes then tell me what other types of files are not supposed to be kept in elf(i.e keep them in other dir and use them at runtime) and where do they keep it in hard disk(i.e how do i locate them manually)?

if not completely then tell me how do programmers, who write very large linux applications, create the executables and the files required by it ?

do they keep all the files required by it in elf itself, that would be a waste of memory! wont it?

Most applications use dynamic libraries that are loaded at runtime and make the executable lighter. You can determine which shared objects are required by an ELF using the command ldd. In order to discover which other files are provided and required by an application, you can get an idea looking at the files installed by the relevant binary package (and eventually its dependencies). On a RPM-based system this can be accomplished by the rpm -ql command. If you don't know the name of the package that provides a particular executable you can always try:
or eventually

The command : rpm -ql chess
displays the files for the installed package.

And : lesspipe.sh chess-1.0-24.fc11.i586.rpm
will show the files in a non installed package.

Some small games can have all graphics, etc.
included in the executable.

If you want to know how : google .. how to build a game ..
or something like that.
