Hi Fabrizo, You seem to be a little confused about what you are trying to do and how, you are over complicating things massively and making a buggy program in the process.
First up you almost never need to call ref() and unref() directly within an OSG application, use of ref_ptr<> does this all for your robustly. By adding the ref() to the code you have effectly introduced a memory leak as the Image will never get deleted as it's ref count won't ever get to zero. All you need to do in your application is do texture->setImage(mynextImage) and that's it. No need for any copying of images, just assign the image and job done, end of story. Robert.
