Quick (probably obvious) Aperture Tip

Aperture is like all of Apple's cocoa programs in that you can simply drag an image file (must be a thumbnail in this case) to your desktop and the result is that you have a preview size image file that you can use for emailing and webposting. If you want a larger size, then you have to export. If you try do this in Lightroom, you'll get the master size file that you imported. Note: This is my first little YouTube movie. I thought I'd post something short very to give it try. More to come.
