If you are a Mac-head, get yourself a copy of iView Multimedia Pro right now. Seriously, go ahead... I'll wait.... Ok, you've just done yourself a huge favor. Congrats! This media cataloging program will astound you with its ease and power. For pictures, fonts, videos, sounds, mp3s, pdfs, documents, etc, and it is fairly inexpensive as well.
Ok, since I'm on a new Mac software note, there is a new version of SoundStudio as well. This compliments iMovie nicely, by the way.
Speaking of iMovie, if you love making videos using iMovie, you should get yourself some Slick Effects from GeeThree, which just released some new bonus plugins.
Ok, stop reading my site and go make some media of your own!
