Looking for software...

I'm looking for software that can put speech bubbles into pictures. I just got my new MacBook and I'm doing a school project. Hopefully my Mac can pull through as my teacher told everyone if they wanted to get a great mark to work with someone who has a Mac

This looks awesome (not free though). There is a trial:

plasq.com - Comic Life - Version 1.4

you can also try looking for an app at cnet's Mac OS X Software Updates and Mac OS X Downloads - VersionTracker or Free Software Downloads and Reviews - Download.com. great places for free stuff.

Although not ideal, you can use PPT if you are proficient at it.
