what app is best for adding text to a slideshow?

Both, but you'll have more fine control with iMovie.

If you use iPhoto you'll need a 3rd party image editor to create the quote slides, import them into iPhoto and add to the slideshow.

Some Image Editors:

Photoshop Elements 9 for Mac - $79Rainbow Painter - $30
Imagerie - $38
Acorn - $50

Pixelmator - $60

Seashore - Free

Portraits and Prints - Free

GIMP for Mac - Free

If you have Pages or any application that can give you the layout designwith the quote that you want for the slideshow you can create the quote slide with it and do a Print ➙ PDF ➙ Save PDF to iPhoto to get a jpg copy of the page in Pages into iPhoto according to this workflow:

One way to get a file into iPhoto as a jpeg file is the following:

1 - open the file in any application that will open it.

2 - type Command+P to start the print process.

3 - click on the PDF button and select "Save PDF to iPhoto".

Note: If you don't have that option go to Toad's Cellar and download these two files:

Save PDF to iPhoto 200 DPI.workflow.zip

Save PDF to iPhoto 200 DPI.workflow.zip

Unzip the files and place in the HD/Library/PDF Services folder and reboot.

4 - select either of the files above (300 dip is used for photos to be included in a book that will be ordered).

5 - in the window that comes up enter an album name or select an existing album and hit the Continue button.

That will create a 200 or 300 dpi jpeg file of the item being printed and import it into iPhoto.
