It may be called something different in Photo shop, but in Paint Shop Pro, it's called clone.
It allows you to select a pixel or group of pixels, and clone them where you want them.
I sometimes get rid of multi player red text this way.
Like this:
Select the clone tool (or whatever it's called in PS)

Next set the size to 1 pixel and select the pixel Directly over where you will start, this way it matches the surrounding pixels. Right click the mouse to select the pixel, and then move down 1 pixel and use the left mouse button to start cloning.

Now just keep going until it's gone.

When it's gone, it may look a little pixelated, so go back over the area with a Smudge or blend tool :

And that's it! Banners gone

Hope this helps someone.
Good luck.
