One thing you can do is display  the "This week in pictures" web part on
a page. This web part automatically displays as sort of a film strip,
starting with the most recently added picture in the library.

When you add this web part to your page, in the web part toolpane, just
put the name of your picture library  in the "Image Library Name" field.

Then, once this web part is added, it will have a "View slide show"
link on it!
