Smooth jagged lines on my photo

Smooth jagged lines on my photo

I have a photo with jagged lines that I would like to be smoothed. After the lines are smoothed, the background can remain either remain white or transparent. You can use any photo-editing sites (e.g. Gimp, Paint.NET, Photoshop e.t.c.)

The photo I want you to edit is this user's profile photo: https://twitter.com/ravorne - after you're finished, please send me an attachment so I can see your work. Contact me if you have any questions.

Thank you!
