Relative paths work to whatever the current working directory (cwd) is.
You can determine what the cwd is with getcwd(3)
and you can change it with chdir(2)
These are unix calls, but I think they're valid in Windows
as well (they're both POSIX).
If your program is invoked from a shell, the current directory
will usually be the dir the shell was in at the time.
But if the app is invoked from a desktop shortcut or a file
browser (like the 'Finder'), then the OS gets to decide what
the cwd is.

There shouldn't be anything special or unusual about FLTK's
image functions; they should act just like fopen()/open().
So if you specify a relative path such as "foo.jpg" or
"./foo.jpg", it should resolve based on whatever the
getcwd() path is.
And if you want to set the cwd to something specific,
put chdir() at the head of your program, so that all
relative file references will work relative to that.
HTH.
