Hide image and set size to 0

Hi there,

Is it possible to hide a leaf or folder image and make image size to zero, I was able to hide image using blank.gif but when i used setImageSize(0,0) it does make any difference, I have many columns in my table would like to use even space that blank image occupies.



Be sure to use grid.setImageSize before data loaded in grid, this command will not affect already rendered items.
Also, please try to use command as
