How to make your Facebook timeline cover clearer?

[Ailee]

I just save pictures I find on the internet that I find pretty or interesting, but every time I upload it to Facebook, the cover is so blurry. Does anyone know how to make it any clearer? I have Photoshop CS4 if it is needed

Just increase the pixels/ image size to one that is the exact size of the cover space. Having a larger picture then sizing it down would be your best bet.

The picture has to be taken with a higher resolution camera. Most pictures look clean at a normal size but when you zoom in, the ratios are what matter. The faster you see the boxes or "pixels" appear when you zoom in, the lower the resolution your camera has.
