Gif Maker

All right, I just spent a couple hours working on my RC plane and I decided to set the webcam up and have it watch me while I was doing it. Now I have a few thousand images in a directory and I kind of want to assemble them all into one gif animation. I know I could do it frame by frame in a few different programs but that is highly time consuming, does anyone know of a program that will allow me to just select a whole bunch of images and it automatically puts them in frames and forms a gif or swf out of it??

Im guessing you don't like Windows Movie Maker...

Never used it, although I did find a program that converts a series of jpegs into an AVI movie and have gotten what I needed to be done done. Provides useful feedback on the buidling process for my plane :)
