Best Answer

You're constructing one filename out of lots of them. You're also assuming that the files are listed in order. You need to get the frame number from the file name.
Try this:
I = {};
for f = 1:length(files)
  file = files(f).name;
  frame = num2str( file(1:find(file,f=='.',1)-1) );
  if frame >= 82 && frame <= 118
    I{frame} = imread(fullfile(path,file));
  end
end
Now you have a cell-array where the elements I{82} through to I{118} will contain your loaded images.
