If you simply store JPGs directly then this will work for your app.,
And this will be cross-platform.

But you should understand that such pictures of your db will not be
correctly displayed in future Valentina Studio, because it will not know
that this is pictures.

If you can live with this, then no problems.

Chuck, 

In V4RB exists 2 new functions.
They are not documented yet.

    GetFormatedPict() as String
    PutFormatedPict(inPictType as Integer, inPictData as String)

As picture type you should use the next numbers

    kFBL_Unknown             = 0,
    kFBL_MacPict             = 1,
    kFBL_MacCICN            = 2,
    kFBL_MacIconSuite        = 3,
    kFBL_MacGWorld            = 4,
    
    kFBL_WinDIB                = 10,
    
    kFBL_JPG                = 20,
    kFBL_TIFF                = 21,
    kFBL_GIF                = 22

Try this and let me know how it works for you.
We have use self such way for Valentina PHP module.

Using this way you will be compatible with all other Valentina products.


And yes, you still need convert it to String object.
