if you constantly get the text written about your aircraft or ai aircraft in screenshots and want to edit this, then open up your image in any free or payware image editor and click on the select tool, and then hit the "delete key", once you are there hit on the clone stamp and mouse your way around the square markers/transparency squares and do your best to blend the background it to look like it was...
if it's too fuzzy or isn't perfect use any of the effects/blurs to your liking...
when ready hit save and you are done...
if reading this is too hard on the eyes or you need a chance to figure it out another way here's a youtube vid with the same thing
