One Piece Forum

@Smiley26:
You can browse using the "All Images" gallery if you want to see every image at once rather than a bunch of small galleries.  I don't mean to be rude, but I think you should familiarize yourself with the wiki system.  Many of the points you brought up are actually addressed in the basic functionality of how the system works.  For example... 

This image pops up in the overall One Piece image library.  If you look at the right-hand column you'll see an area called Galleries. 

• This is a One Piece image so it is connected to the overall One Piece gallery.  If you're looking for pictures of One Piece, this will show up.
• This image is specifically from episode #488 - A Desperate Cry - Seconds of Valor that Change Destiny and it is connected to that episode's gallery.  This means that if you were on the episode page for 488, the image would show up.  If you want to specifically search for images from episode 488, this one would show up.
• This is a picture of a character named Trafalgar Law.  The image is associated with that character, meaning that if you were on his character page, this image would show up.  If you wanted to search for images of him, this picture would show up.

  
There is no need to choose any one association over the other when you can associate it with multiple wiki articles.  As long as images are properly cataloged, like they are in the One Piece wiki, you can have a ton of them and have them be easy to locate via a variety of methods (ie series, specific episode, character, etc).  The only time pictures get unmanageable is when they aren't properly tagged and associated and you have stuff like an image of Luffy that isn't linked to Luffy and is just floating out there.
