I just want to mention a free (with nag screen) image/video viewer which I have found to be a useful utility when going through images and videos to include in a project - the Faststone Image viewer. I have a found it to be very useful when going through media from my camera before copying the files to my hard disk, and also when collecting media for my project.
I use the viewer to browse through my media (images/videoclips) and just drag them from the viewer direct into the relevant bin in Vegas Movie Studio. Link below:
