I see that your new (cuz yknow you said you were) so I wanted to give you a tip.

If you want to make your texture the image on PMC but it gets blurry here's how you can get over that.

first, you want to open your texture in an image editing software (I would defiantly recommend paint.net because it really good and I will be using it when describing how to do this). Then go to file, then new. when you do this you want to make the size a multiple of 16 (or a multiple of the size of the texture {EX: x32,x64,ETC}) I would use 512 x 512. Then copy the original texture and paste it onto the new image. Then size it up so it fills up the entire thing. You will notice that its blurry but you can change it from billiner to nearest neighbor and it will be solved. Then just use the new image for the picture on pmc and boom it will be high def.
