Can you assign the data to a stream and then to a TJPEGImage ?

#include <jpeg.hpp>

   TJPEGImage *JPEGImage = new TJPEGImage;

   JPEGImage->LoadFromStream ( .... )

   Graphics::TBitmap *Bitmap = new Graphics::TBitmap;

   Bitmap->Assign ( JPEGImage);

   // use bitmap        \

   delete Bitmap;

   delete JPEGImage;

Hans.
