@JMarcell where did you get the original picture from?

You could of course scale it to something like 1024x1024, but it's better to find the source and check if it's available in a higher resolution, looks better ingame
@deen due to copying-mapres-from-other-maps several ones have the mapres in wrong reso as it was for sure saved by downloading forum's image thumbnail (thumbnail size is exactly 600x600px) in the first place(edited)
