See a Larger Preview of the Thumbnails?

There are two ways to do this in the Import window: (1) If you want to see all the thumbnails much larger, just click-and-drag the Thumbnails slider (below the bottom-right corner of the center Preview area) to the right—the farther you drag, the bigger the thumbnails. If you just want to see one image really large, double-click on it and it zooms to fill the Preview area (as seen above). Want to zoom in a little tighter? Just click once more on the zoomed-in preview, and it zooms in a bit more. To return to the thumbnail Grid view, just press the letter G or click on the first icon below the bottom-left corner of the Preview area.
