So, I was making a head... With resolution being 512x512.
The head had stuff not only on its front, but also on the sides and back.
Thus, just a pic from the front side of the game from in game wasn't enough.
So, I decided to make a spinning preview out of it.

But what did I get?



In Toribash, the heads aren't that big.
And that's where I need help.
Is there any way to resize the spinnies to the Toribash head size with GIMP?
There shouldn't be any quality loss.
Is it even possible with GIMP?
