That's what I thought regarding class way, but after banging my head against the wall all day, I couldn't help wondering...

There is no warning log and I have that property set to true.

Here is a snippet from the debug log:

Database_SqlSelect_1...
    PARAM: instance = 550985152
    PARAM: inQuery = "SELECT pCoverPic  FROM Images WHERE nId = 16"
    PARAM: inCursorLocation = 2
    PARAM: inCursorType = 3
    PARAM: inDirection = 1
return object = 560355056

Cursor_GetRecordCount...
    PARAM: inCursor = 560355056
return res = 1

Cursor_GetFieldByName...
    PARAM: inCursor = 560355056
    PARAM: inName = "pCoverPic"
return object = 551351024

Picture_WriteAs...
    PARAM: inPicture = 560269840
    PARAM: inQuality = 50
return

Cursor_UpdateRecord...
    PARAM: inCursor = 560355056
return

Database_Flush...
    PARAM: inDatabase = 550985152
return


It doesn't look like anything is going wrong, but when I open the DB using VStudio, the field is listed as <empty>.
