how about

fullfile(fileparts (which('an_m_file_in_the_dir.m'), 'maze.png'))

or something like this

I often put a function in directories of interest like below for similar 
reasons:

function path = linearmachinerootdir()

    path = getmfilepath(mfilename);

end



where getmfilepath. is just



function filepath = getmfilepath(mfile)
% getmfilepath: gets the directory containing an mfile
%
% Syntax
%
% filepath = getmfilepath(mfile)
%
% Input
%
% mfile is a string containing the name of the mfile for which the
% location is to be found, the .m extension is optional
%
% Output
%
% filepath is the directory path containing the specified mfile
%

    if exist(mfile, 'file') == 2

       filepath = fileparts(which(mfile));

    else
        error('UTILS:nofile', 'm-file does not appear to exist')
    end

end
