If you have them on your server that has ffmpeg installed, you can run this unix command and it will grab 10 frames from each video and name them as video_name_1.jpg, video_name_2.jpg and so on. Then you can just pick the best looking frame and work with it.

for i in *.flv; do ffmpeg -i "$i" -an -ss 00:00:03 -an -r 1 -vframes 10 -s 160x120 -y `basename $i .flv`-%d.jpg; done
