In Lion one is called thumbnails and you can drag the divider bar to change the size.īy dropping multiple files on Preview you can now do batch operations too, like adjust the size, or flip and rotate. Before Lion one of these buttons is 'Contact Sheet' when you click on it a Slider will appear and you can adjust the size of the thumbnails. On Lion there wil be buttons at the top by the Search box. Preview will open with all the images in a side bar and some buttons will appear on the bottom right in OSX before Lion. Select the group of files you want to see, or just drag the whole folder to the dock, and drop on Preview.Ĭheck in Previews presences under the General tab and check the 'Open groups of files in same window' is checked. To open up the power of Preview, I keep it on the dock so it is handy all the time (doesn't have to be open and running).

Preview can be used for much more than just a quick glance at an image file when you get out of the habit using it like on a Windows machine.
