V4RB BLOB HELP! -- Solution

[Jason Moehlman]

I just wanted to thank you for your help.

The final solution for me was the MBS Plugin.  It has some great 
functions for this work.  I have only been working with it for a couple 
of hours, but I am working.  Best of all according to the docs QT is 
not required unlike the RB picture functions.

I have some more debugging but the hard part is done and everything 
works.  FYI while the image processing takes a little time, reading and 
writing the data to the DB with ReadRawData and WriteRawData isn't even 
noticeable on a Mac.

Thanks again!

Jason
