Hope this helps... imgNameList=char('camerman.tif','Image.jpg','image2.jpg'); pause on; for i=1:length(imgNameList) a=imread(imgNameList(i,:)); imshow(a); drawnow; pause(1); end
%%% the above code runs only once %% better you use timer .

% if you want to use with timer %% create a timer %%% create a new file with following code and name it as main .
global indx indx=1; showTimer=timer('timerFcn',@slideshow); set(a,'ExecutionMode','fixedRate'); set(a,'Period',2) %% 2 sec delay start(a)
%%% create a function function slideshow(varargin) global indx imgNameList= char('img1.tif','img2.tif','img3.tif'); indx=indx+1; if indx> length(imgNameList) indx=1; end imshow(a); drawnow;
%%% Now run main file

You have two create two files. one that is your main file normal script other is function file.
create a new file and save it as slideshow and enter following code
function slideshow(varargin) global indx imgNameList= char('img1.tif','img2.tif','img3.tif'); indx=indx+1; if indx> length(imgNameList) indx=1; end imshow(a); drawnow;
%%% End of function %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Now create new file and save it as you want with following code,
global indx indx=1; showTimer=timer('timerFcn',@slideshow); set(a,'ExecutionMode','fixedRate'); start(a)
