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.

Note, edited original post. Had not noticed your assumption about the files list indices being the same as the actual frame numbers.
