Is it possible to have a background image for the whole window and not every split pane itself? I can't find how to do it anywhere.
This is a year late but I had the same question and ended up here.
There is no way to set a single background for the whole window but if you untick
Use Lion-style Fullscreen Windows in the
General Preferences, then you can set your background semi-transparent and have your wallpaper act as a single background when
iTerm2 is in full screen.
In my case this achieved the result I was looking for in the first place and is an alternative to what you were asking for.
Here's what mine looks like now:
You could also set transparency to 100%.
Note: You may also want to tick
Auto-hide menu bar in non-Lion fullscreen in the
iTerm version 3.3.0 (in Beta as of June 2019) you have a setting for this:
Preferences > Appearance > Panes un-tick
Separate background images per pane

Works, and iTerm2 too Mar 2 at 22:43
In Iterm2 go to Preferences:
Profiles > Window > Background Image
is there a way to set this through AppleScript?– user53981Jul 5, 2019 at 19:51
