Hehe no problem Fran~, you know I actually saw the avatar in question before, but as I still didn't know that Nami has long hair now, I thought that avatar was made of many pics from different same-hair-colored girls (to tell you the truth, I wasn't really paying attention to it either
)
Oh well, as I've stopped following One Piece (not because I didn't like it, but because my time has been missing a bit too much those last years), I'm really not up-to-date with the manga, so I'll let another moderator (who actually follows the manga and anime) deal with it
The pic you posted are fine (they don't give any hints of scanlation source, and they are small <- it's not like you posted the whole manga page).
See you around~!!
nb: same with Naruto, don't ever spoil me a Naruto event in the Bleach manga thread, or a kitty will die...j/k
