Javelinphotos thumbnail (GIF)

I'm working on a website for a friend, he's a photographer & intern at the dutch ministry of defence. the buttons are already working.

note: the gif is kinda slow, works much better in browser ------->>>>
You can see it working here:

it's a PNG sequence, I might try it in canvas too,
