Picasa

Picasa can be used to perform nearly any operation that involves pictures. Instead of using a different application for each operation, you can use this universal tool to organize your pictures, create collages or slideshows and much more. The application comes from Google, so naturally, you can expect to find a wide range of useful features, which can make your life easier.

Picasa will offer to scan certain folders or your entire Mac for pictures, when you run it for the first time. Once the scanning process is complete, the application will organize the found pictures in separate folders, according to their creation dates.

The contents of the folders are displayed on separate ribbons, in the central area of the user interface, which makes it quite easy to browse through your pictures. You can just scroll through your pictures, using the mouse wheel or a scroll bar. Alternatively, you can jump directly to a specific folder, by selecting it in a column, on the right side of the interface.

A series of options are available for each folder. They allow you to play the contained pictures in a slideshow, create a video presentation or a collage. You can also sync a folder's contents to your Google Plus account, by simply clicking a switch next to the folder and share it via direct link.
