hmm,
i thought so too, but this is not working for me with files of type file (DT_FILE) (i use it for mp3 files) but for image fields it does. 


But i think i got it by diggin into ZMSGlobals.py:

If a file is generated by FileFromData it is instanciated with mediadbStorable=False

If i change this to True i get the resulting file with attr() / setObjProperty() saved within the mediadb storage.

Not shure if this is correct/usuable at all or gives any bad side effects (seems not to me so far) - if it is OK you may use my diff as a fix:
