Tiled Background Glitch Driving Me Insane!! Please Help!

Hi there, I hope I am posting this in the appropriate place, if not, let me know and I'll remove it.

It is definitely a case of being a beginner and not knowing how to troubleshoot the problem myself, though I have some ideas.

So, here goes.

I'm trying to do the beginner's tutorial, but, every time I load up the tiled background image, it looks fine in the editor, but when I close the editor, the image is resized from 256, 256px to 512, 512px, and it goes all blurry. I have no idea why this is happening, I really want to get started making games, and this is driving me insane.

Here's a screen shot:

Please help, thank you!

Solved the issue!!!

For anyone else who may be having this problem, I just had to turn on Anisotropic Filtering in my graphics settings.

Hi! That was instructive! My Problem is a bit different though! It is when I run it becomes blurred, hazy and becomes colossal!

Please help
