Microsoft's Slide Show Help

Below is a cut out of the Portrait's Slide show. I've compressed it way down to load quickly.

notice left and right of the thumbnails (little pictures) there are arrows. The one to the right is solid, the one to the left is hardly visible and is simply an outline (telling you that there are no more thumbnails to the left.

To enlarge the thumbnails, just click on them

To move the thumbnails and view the others, click on the arrow to the right.

 

Here is the arrow blown up.

The problems you might encounter are these:

Thumbnails do not show up or the arrow does not show up.

This happens because of your cached picture area (where pictures are stored on your disk) so if you have these problems, you can right-click (click and hold down the right button on your mouse) where the thumbnail should be and choose from the menu, Show Picture. You can do this for the arrow too, but it is hard to find. So take a look here where it should be. You can also just click on that area and the Thumbnails will move.
