Consider a drawing in which I refer to the drawing template file housing my logo-bearing, custom title block (I point to the .slddrt in the `Sheet Properties' configuration window).  I choose `Sheet Properties' and toggle the `display sheet format' variable to off.  I observe that the title block content and dividing lines/field boundaries are no longer visible, however, the logo remains.

My question is: What is the recommended practice for inserting a logo, and is there a way to insert the image file (I'm using a .png) which allows the inserted image's visibility to toggle along with the title block content.

Any suggestions/comments are greatly appreciated.
