You could make a proper 'presentation' using PowerPoint or a similar program (such as Impress, which is part of the free OpenOffice suite of software). However I wouldn't bother as the following is far simpler:
Download and install Irfanview onto your laptop:
http://www.irfanview.com
[It's an outstanding image viewer (that's about a zillion times better than the rubbish that comes with Windows) that's also got lots of advanced options, such as a slideshow facility]
Put all of the pictures you want to use into a folder.
Open Irfanview.
(If the window isn't full-screen, maximise it)
Go to File > Slideshow.
Use the navigation bit at the top right to navigate to the folder you're using.
(The list of all the files in that folder will now appear in the pane at the top right).
Click on 'Add All'
(The list will now also appear in the pane at the bottom right)
Put a tick against 'Loop Slideshow' and 'Hide Cursor'
Remove the tick against 'Show text'
Adjust the time interval (for the slides to change) to your choice. (I suggest trying 'Automatic after 10 seconds').
Click 'Play Slideshow'
Job done! (Use 'Esc' to terminate).
My technique will give you a slideshow of the same type as you would get with an old-fashioned slide projector. (i.e. as one picture goes off the screen, the next one replaces it). That will probably be good enough for what you need. However if you'd rather create a full 'presentation' (where slides can, for example, dissolve into each other as they change) then download and install OpenOffice:
