I want to start a campaign and include an animated gif. The adwords guidelines say that animation of graphics can have a maximum duration of 30 seconds. But the gif consists of 2 images that should alternate every 3-4 seconds to draw attention to the effect of the product. I don't see how I can make the animation stop after 30 seconds, it's an endless loop as far as I can see. I use GIMP to create the gif.
Try searching for software that optmize your anination in quality and duration, google it with keywords like "freeware optmize gif animation" or check software available at www.download.com
