Hi all, I got my MacBook a few days ago, but I can't seem to figure out how to zoom into pictures, the "zoom" slider is disabled. My camera's 8MP (Canon EOS-20D), so I highly doubt iPhoto is preventing me from zooming because the picture is too small. Can someone help me please? It won't let me attach a screenshot, Command-Option-3, the file size is too big. I'll just tell you that the zoom slider is grayed out.
