OK, let's try this again . . .  :-)

I post my cel (I KNOW who the character is). 
Poster #1 has to GUESS who it is and then poster
#1 posts a cel of another character for poster #2
to guess who it is, and so on . . .

You, the one posting the cel, have to KNOW, what
your cel is.  

YOU 'CANNOT' POST A CEL YOU DO NOT KNOW WHO/WHAT
IT IS, OTHERWISE, THERE IS NO POINT IN "GUESSING".

The trick is to post a cel from a series or a
character that you "think" OTHERS may have
difficulties guessing.
Hope this clears it up a bit.

Now, here is my cel.  Can you 'GUESS' who this is
(you don't have to be 100% certain who it is, but
take a guess)?  :-)
