I definitely prefer to see galleries where the 
cels are accompanied by a commentary. This can 
include episode or scene identification or 
description, but also can mean a commentary of 
why you like a certain cel. Commentary makes it 
much easier for someone to more fully appreciate 
a gallery of cels from shows that they have not 
seen.

But I always try to AVIOD major spoilers. I don't 
remember if I have any of them up now, but there 
are a few cels of mine for which my first comment 
is: "I can't describe the scene without spoilers, 
so I won't." Instead, I make sure to say something
else of interest about the cel - a note about a 
detail I like, or I point out something unusual. 
("This character usually isn't painted this way",
"notice the _______". . . etc.)  These would be 
things the importance of which would otherwise be 
lost on someone who hasn't seen the the show.

Another thing I like that I don't see much of 
(which I'm trying to do for my own site) is to 
see some kind of comment on why a person likes a 
certain show so much. You might buy a handful of 
cels from a show you just found interesting, for 
no other reason than they look nice. But if you've
got fifty cels all from one certain anime. . . It 
screams there was something special to you about 
that ceratin piece more than others. ^_^  So far, 
the only place I have done a page like this is 
for Psychic Force. ^_^ (See the link at the top 
of my Psychic Force cel page. ^_^) But I have one 
in the works for both Eatman and Vampire Miyu. 
I'd love to see more people do the same kind of 
thing! ^_^
