Library View
This is the default view when Picasa starts. Any time you’re dealing with more than one image, or browsing to find one to work with, you’re spending your time here. Let’s break this down.
Menus and toolbars
At the top of the screen is the normal collection of menus and toolbars, and most of these do just the things you might expect them to. We’ll deal with these as they come up. Note where the help menu is though. It’s very useful, but has an annoying peculiarity that’s becoming rather common. None of the help info is stored locally, so it will only work while you are online.
Folder list
Light box
The major portion of the screen, and the one you’re likely to spend most of your time, is called the Light Box, after the boxes traditionally used by photographers to view and compare slides.
The light box is similar to the thumbnail view in Windows Explorer, and mostly behaves the same way, except for one very strange but handy feature. If you scroll out the top or bottom of the view of the older you are in, it just happily continues to the next or previous folder (or album).
Once you actually click on an image, the Folder List highlights the current folder again.
Status Bar
Directly underneath the Light Box is the status bar. This shows you a whole lot of information about whatever is currently selected. Keep an eye on it. It’s very handy.
Underneath the Status Bar are two more important features, collectively known as the Photo Tray.
Photo Tray
On the right are all the tools you need to deal with moving your images onto the web, printing them, blogging etc.
Top right of this tool is a slider to let you change the thumbnail size in the Light Box. To the left are some buttons for dealing with individual images, including rotating and favouriting (alright, favoriting) them.
Edit View
That’s it. Click the Back to Library button, top left, or hit the Escape key to return to the Library view.
