I've been getting lots of questions about this.
To be honest, it's not that hard =S.
RIGHT CLICK IMAGE. THEN PRESS OPEN IMAGE TO MAKE IT BIGGER
So just incase you can't see (which i have a feeling it'll be like that)
1) Right click the file
2) Click Rename
3) Erase ".zouter"
4) Type ".avi"
5) Watch the video!
Easy right? Haha.
