@Jim100361 Thanks for the help. I should've mentioned that what I want to avoid is redoing the gradient, cause I never did it myself and I like the way it is apart from the broken part located at 12o'clock.
@ventor1 I'm trying to custom mod my PokerStars tableskin, so that is why I don't want to put in on the center of the image as the PokerStars program would probably not understand that change
@pdnnoob That advice about flipping horizontally and vertically was really good, I did that and copied the flipped image over the bottom part of the picture. There are some sharp edges still inside the pic though. I'm new with the feather-tool. I just DL'd it and put it in my effects folder and have it show up under effects in Paint.NET too. Okay so I read that it only works if there's no background layer and the sharp edge has to be next to transparent area. I did both, but there's a problem, feathering doesn't fix the sharp edges inside the picture since they aren't next to a transparent area, so how to use feather-tool this way?
Before I ever used feather-tool I thought it's something like a paint brush type of thing that makes areas blurred that you draw/paint on, but seems like it will always edit the full area inside the selection (or rectangle select). So to me it seems to be doing exactly what I use Gaussian Blur for... Dunno if I'm using it right, they really seem like almost the same thing.
Here's what I got currently. Again need to find a way to fix the sharp edges inside the pic somehow, since it's not possible to do with feather-tool since the edges aren't next to transparent area.
