I'm not sure if this is what you mean, but all the matlab example images are in this folder:
C:\Program Files\MATLAB\R2013b\toolbox\images\imdemos
You could also use this code to find the directory:
function varargout=demoimgs
pth = fileparts(which('cameraman.tif'));
D = dir(pth);
C = {'.tif';'.jp';'.png';'.bmp'};
idx = false(size(D));
for ii = 1:length(C)
idx = idx | (arrayfun(@(x) any(strfind(x.name,C{ii})),D));
end
D = D(idx);
for ii = 1:numel(D)
fprintf('%s\n',D(ii).name)
end
if nargout, varargout{1}=pth; end
this will list all the demo images. Written my Matt J^
