This special type of MSN Display Pictures is supposed to change automatically according to your mood.
There are two ways to use this feature:
1) Using emoticons like
and
in your conversation will trigger the Dynamic Display Picture to express emotions corresponding to the smileys. If you're the kind of chatter who types more emoticons than two syllable words, you better turn this option off.
2) By clicking an option called "Change mood to" or right-clicking your Dynamic Display Picture, you will be able to set your DDP according to your current mood. As soon as it has finished loading, it appears on both your and your contact's screen.
You have to buy these from Blue Mountain, recently, they disabled the pin that let you get them for free, so unless you can pay, you won't be able to have one now.
