As of late, I have been getting into astronomy and I have been finding a great deal of pictures dedicated to that subject. I have also found numerous .gif images that pertain to astronomy as well. Anyways, I plan on using some of those pictures/files for presentations I will be doing in the fall semester in my Astronomy class. The only problem that I am having isn't while streaming them from a website; the problem lies after I save the .gif to my computer. When I save a .gif to my computer, the animation slows down considerably. It isn't a problem with the smaller files, but with the longer ones (ex. size comparison in planets) the speed is so slow, it almost isn't worth watching anymore. Does anyone know why the .gif images slow down after I save them to my computer, and more importantly, how do I prevent this from happening?
