If you never got around to buying that photo editing software, head over to Picnik, a free photo-editing tool which helps you pretty-ify your snapshots with a few clicks. There are some cool design options along with the basic crop, remove redeye, and resize options. (www.picnik.com)

If you’re ready for some free music, click over to Slacker, which streams a variety of free Internet radio stations across different genres (such as rock and country) and themes (such as party music).
