Hello,
I have experience with jquery, AJAX and PHP. I also have used codeigniter image manipulation library. But it did not have all those effects. But if there exists library or functions for all those effect, then it would be not difficult for me - on some option change I would just send to PHP server, then it proceses and returns some flag that image is procesed, then I would need refresh that image on page. I am not sure how the refresh would workd, because browsers could cache that image, but I guess its posible sort it out using some timestamp to the filename.
But if there is no existing functions to those effects, then its much harder to make them.
