Couldn't find anything about this topic.
I have an animated GIF that contains a tree picture which changes color over time. What I'd like to accomplish is that if a website visitor clicks on a link and the page is being reloaded, the GIF Tree doesn't start again from the beginning. No, the Tree should have the color which it had when the user clicked on the link. So I'd like to store the frame number of the GIF when the user clicks a link and starts the GIF animation on the reloaded page with that frame number. Is that possible at all? The only image library for PHP I have is GD. THink there's no ImageMagick on this server.
Thanks for your help on this!
