Hi Stephan,

Okay I see problem.

As fast workaround you can try to use field BLOB and store pictures using
SetMethod. But this probably will end with bigger db size.


For nice solution of this problem we need to V4MD feature that exists
already in other products: ability to store JPG AS IS, without own vl
compression.

We need all together fight with this problem.
I need help because I am not sure how you Lingo writer can
A) open JPG file as binary file
B) read into RAM it AS IS, so Driector will not expand it
C) send to V4MD this RAM buffer.

You have ideas how this can be done?

May be we need look on third party xtras that work with pictures and JPGs?

May be V4MD should import JPG directly from disk by given path?
Although this require efforts from us. Not implemented in kernel.
