This is what I usually do when I prepare pictures for IMCDB:

I have a movie saved on my computer and I open it in Quick Player. When I see a car I stop the picture and press "printscreen" key and copy the still image to empty word page. Then I copy the picture from Word to Paint so that I can save it in jpg format. This has worked so far. But today when I copied a picture to Paint I noticed the quality was not nearly as good as in the original still image. I tried every trick I know but nothing helped. There must be another way of doing this.

Is it possible to save pictures from Word-file (I mean not the whole file, just the picture) ?

What's the best way to convert mpg still images to jpg ?
