[V4MD] problem with importing jpgs

[Gunnar Swan]

Our software is just now getting into storing JPEG in Valentina.
I'm strongly interested in this subject.
We will do one time import ... then once in database, read only.
Would image degredation be a problem in this case ?

I do have license to vList. Is this best solution at this time ?
