If you want to display images in arbitrary cell types, it probably will be simpler to handle the CellDrawn event, and just draw the image there after the grid has finished doing its default drawing. In the CellDrawn event, you can decorate the cell with custom drawing independent of the actual celltype.
Here is a forum thread that shows how you can use this event to draw images in cells.

Thanks Clay, It works well.
Is there any option to change the back color instead of placing the image at runtime for those cells (Header, Static, and Push buttons and all types)?
And it should have the provision for revert back to the original color which was set while loading the Grid.

The BackColor of a cell is normally controlled through the style.BackColor property of the cell. This should work for any cell unless you are handling some event that prevents this default behavior.
One comment though is that the backcolor of buttons is not control through the style object for the cell. Instead, you will have to handle an event to color buttons. Here is a forum thread discussing coloring buttons. http://www.syncfusion.com/Support/Forums/message.aspx?MessageID=26772
