Downloading and installing Picasa is easy using the Windows installer. Upon launching the program, users can choose where Picasa import pictures from on their PC: select to either search through only My Documents, My Pictures, and the Desktop, or search the whole computer.
At this stage, you can also opt-in to use the Picasa Photo Viewer to view photos directly from Windows Explorer. The viewer can open various file types including .jpg, .bmp, .gif, .png, .tga, .tif and .TIFF, .webp, and .raw extension.
