making a video using screenshots

Epichall

Quite a while ago, I made a 3D bedroom and took about 160 screenshots of it from different angles, saving each screenshot as a *.jpg. I was experimenting with "camera paths" at the time.
I've come across the photos again (the set has long-been dismantled) and so I was wondering if there was a free computer program anywhere that would let me combine these screenshots into a very short film. At 24 frames per second it would run for about 6.5 seconds. 
It has to be a movie, not an animated *.gif or a slideshow.
Any help or advice would be appreciated.
