I just did this and it worked.

Created a table with field ImageFile. Put a few records in the table with BMPs files in the field like "Graphics\Bitmaps\Assorted\Balloon.bmp". Then create a form and added a commandbutton with this in the click;

SKIP
Thisform.Image1.Picture = TableName.ImageFile
Thisform.Refresh()

When I clicke the button the image changes to show the file in the field.
