I do the same as
Red (Photoshop) and I think most people do use still photos rather than video captures to create animated GIFs (it's one less step to do... you don't have to create the "stills" from the video in the first place if you use the screencaps someone else already created

). I use the
ML Love and
ML Forever screenshot albums a lot (thanks to both of those sites

).
To create an animation in Photoshop, just go to the "window" menu and select "animation" to reveal the animation tools. The help menu in Photoshop can explain more how to use this feature. I've only ever created animated smileys, not ML animations, but it was very easy for me to learn how to use this feature from the "help" instructions.
(Here's one I created for work

Alternatively, you can create them online (though with much less control and more limitations on how many still images you can use). One such site I've used before is:
http://picasion.com/
You just upload your 3-4 photos and pick a size and a speed from drop-down menus and voila, you've got an animated gif. I'm sure there are other sites ... just Google "animated gif."

Hope this helps. One of the things I love about this board is how we all learn from each other. I have picked up so many new "skills" from this place.
