[VApp] How do I import a picture?

[Douglas Wagner]

Hello:
I've attempted to import a JPG file into both a BLOB and a PICTURE 
field using Applescript but without success.

I note the manual instructs one to "...create and fill in RAM header of 
picture record, which contains 4 + 4 + (2 + 8) = 18 bytes. Write this 
header into Picture field and then append context of JPG file (this 
context must start from 0xFFD8 marker)".

What does all of this mean? Can someone give me an example of a RAM 
header and explain how this ought to be used.

Thanks: DW
