You ask about moving picture from 1.x db to 1.x db?
Or to 2.0 db ?

In C++ such ways exists. But V4MD developers are not so advanced,
And the main Director itself do not allow you easy work with RAM.


In 2.0 we can have SaveToFile() LoadToFile() functions.
Which read/write BLOB as is.

1.x do not have such methods.
