DBAdvGrid - Additional column with picture

Hello,
how can i display pictures in DBAdvGrid, which is not part of the dataset?
Background:
The filename of the picture can be created, based on the data of each record. I can display the relevant picture in each row with OnGetDisplText with help of the img-tag. Nice on display, but during printing the picture will be displayed in original size.
Therefore i search an other way to load pictures in the cells. If i will do this in the event OnGetDisplText, it doesn't work (tryed with CreateFilePicture or CreratePicture).

Has anybody an idea to do this in an DBAdvGrid?

Best regards
Marco.
