Banner Ad Issue

Whenever I upload my banner ad, it’s all fuzzy and cramped, and I don’t know if it would look like that when I release the ad. Is this just a glitch?

First picture is the ad when I upload it, second is the actual ad.

Apparently the preview always try to fit the image within the box rather than properly scaling it to the fixed original aspect ratio. Don’t worry, the ad displayed is normal.

Okay! Thank you very much, just released the ad.
