I am loading a jpeg byte[] from a database and i am trying to load this into 
a bitmap object wher i can resize it. I can do this by copying the byte[] to 
a file and using the standard bitmap load from file functions;

Is there a way I can do this without having to goto to the disk?

I assume you mean load it from a file using the constructor?

You should be able to use a MemoryStream which accepts a byte[] in its
constructor and then pass this Stream to the constructor of your
Bitmap.
