There is a column property called DynamicCurrentControl. You need to create a control for *each* picture you wish to be displayed, then set the DynamicCurrentControl property to display the appropriate picture control. For example, create three picture controls: imgMyPic1, imgMyPic2, and imgMyPic3. All of these go into the column. Then, in the Init method of the grid, set the column's dynamic current control to select the appropriate image:

This.grcMyCol.DynamicCurrentControl = ' IIF(FieldVal = 1, "imgMyPic1", IIF(FieldVal = 2, "imgMyPic2", "imgMyPic3"))'

Hopefully you don't have too many different pictures to display! We're using this method successfully, and it the performance is more than acceptable. Good luck!
