I posted an issue a few days ago about how I'm using a flash remoting framework known as amfphp. I have no control over this.

I am needing to create thumbnails based on images (Primarily jpg and gif but would like png support).

I know how to create a thumbnail utilizing a header() but unfortunately I cannot utilize header() as it's already output by amfphp and at runtime it's throwing a nasty "Headers already output" error.

Is there an alternate way of taking an image - creating a thumbnail without utilizing header()'s.

Thanks
