http://www.gyazo.com gives two free apps that lets you take pics but uploads them to their website (you can copy to your hard drive by right click and save image as...)
one program icon is a pic with a pen -- that will take still photos in png format
one program icon is a filmstrip with a loupe -- that will take moving pictures for a second or two in gif format
the only thing with the gif program, is that kittycats movement is random. when you take the image, anything that moves in the next second or two will be recorded. Sometimes you have to take pics several times before you get movement that you like. I took this pic several times before she did more than sit and blink at me, lol. She was like, "What is my motivation?", lol. Actresses, sheesh.
