From time to time I've seen ads and WW posts with quite a few pics in them. Makes for a lot of scrolling. All good since the more info the better. So this isn't about the number of pics being used but whether or not to combine them into an animation. (Example of a St. Pat's promo below)
Two ladies I know prefer them over stills as they "percieve" that it's harder to snag them for use by other providers. Not the case but it makes them feel better. Sometimes you can work them into a cutesy theme.
So. Do you prefer stills, animations or a mix?
