To VFPT:
you can considers to change this property name with this schema:
ControlSource ( that is an expression that returns a type memo or blob )
Value this is current PictureVal renamed.

Making therefore,
- if I put a image in a grid column, with Sparse = .F.,
I can have a automatic bind of the Image control
to the the Blob field that contains the rows images.

- I can edit a Blob field:

** Image.Click
this.Value = FILETOSTR(GETPICT())
* if controlSource have a Blob field expression, this is filled with picture binary data

ControlSource + Value is the natural choice into VFP Language for implement
a Blob control.

Thanks
