I will happily have a go at shrinking images for people.

Some hints for those who try this themselves: if using gifs, reduce the number of colours used. When animating, if you want one frame to appear for longer than the rest then rather than repeating it use something like Microsoft GIF Animator that lets you set per-frame timings. Also, make sure you;re using the most approiate file format. As a rule of thumb, GIF for line-art, small stuff and anything animated. JPEG for photos and high-colour stuff. PNG for high-colour lineart, and large stuff where quality matters. For the same image, a JPEG will usually give the smallest file-size, but will also have the greatest loss of quality.
