Simply put, there can must be no more and no less than two people in your icon. Any combination of people is fine, and feel free to use multiple pictures in one icon (like the one I'm using for posting this, for instance) because if you want an icon with Chacha and Toshi, you'd be hard-pressed to find a picture, I think.
And, as always, I went ImageShack happy so there are a bunch of pictures you can use (but aren't limited to); a good number of them are from Itsumademo: A YOU Fansite, and there are others there that I didn't upload.
[+] Icons are due by midnight on Saturday
[+] Two icons per person are allowed.
[+] No animated icons allowed.
[+] You do not have to try and fit every single person in GacktJOB into your icons.
[+] Submit your icons to this post (comments are screened) in the format:
I don't know why I decided to post them in categories... but here they are. In categories.
Gackt and You:
Gackt and Ren: (no, I have no idea what Ren is doing)
Gackt and Masa:
You and Chacha:
You and Ju-ken:
You and Ren:
And of course, there are a bunch of pictures we've already uploaded that would work well.
