Hello, I have the following piece of code and it does not work with GIFs. It simply produces a 0ko image. It works fine with JPGs.

ImageIO.write returns a boolean indicating success/failure. If you had checked it you would see false here. The J2SE ships with a GIF reader but not a GIF writer. That's because of copywrite issues some time ago, but the copywrite has since expired. There are several 3rd party gif writers out there: google for them. You can also download and install Sun's JAI Java(TM) Image I/O API which provides more reader/writer plug-ins for ImageIO. In the documentation for it:
It states: An ImageWriter plug-in is provided for the Graphics Interchange Format (GIF). Animated GIF images may be created using the standard sequence writing methods defined in ImageWriter. By default the writer creates version "89a" images.
