You don't have to close Matlab, just
close all
Probably you have opened files using fopen, and forgot to close them using fclose?

thank you all... it worked fine with
fclose('all');

I think that's somewhat dangerous unless you know what is open. I think you should open and close each file individually. That's the cleanest way to do it. If you just blindly call fclose('all') then it's possible that you might close something you did not intend to. That's why it's better to close each file independently and close it when it makes sense to close it, not just at some arbitrary time later, blindly, and with a sledgehammer.

Does the file even exist? Try this
if exist('Face Granules\FGr13.jpg', 'file')
uiwait(helpdlg('File exists'));
else
uiwait(warndlg('File does not exist on the search path!'));
end
