To make animated gifs on photoshop

using PhotoShop Image Ready.

There's a really simple animation program called movies 13 which you can get from here:

However, I'd ask someone before downloading it in case of viruses and stuff. Or scan it first or something. Just be careful.

I'd recommend ImageReady because if you have Photoshop 6 or above, you should have it and it is safe and an easy transition if you know photoshop.

Ive made animated images in photoshop 5.5 but they are spp files and it's impossible to find somewhere to upload them

I use graphics gale, its a free program and pretty easy to use. :)
