Where are my photos?

In Snow Leopard with iPhoto 09, the original image folder is somewhat hidden, you can go to this folder by right clicking the iPhoto Library > Show Package Content > Original.

If you need an access to this folder often enough, just create an alias (Command + L), or if you don’t want the system to add the word alias in it, just press Command + Option and drag the folder outside the original folder, don’t worry, you still know this one is an alias by looking at the tiny arrow at the bottom left-hand corner of it’s icon.
