According to Fan Forum's spoiler rules, filming location pics, episode stills and sneak peeks are considered spoilerish. This thread is the best way to discuss them without spoiling the ones who wish to remain spoiler free.
Information is considered to be a spoiler if it details something that has not yet been broadcast anywhere in the world

The following limited spoilers are allowed in a designated discussion thread on the forums here as long as the title includes the word Spoilers:

• Information officially released by the network such as sneak peaks, filming pictures and episodes stills, or cast interviews that hint at future storylines can be posted in the designated spoiler discussion thread at all forums.
• Spoilers should only be discussed if they meet the above limited conditions and any further spoilers should be discussed at the Spoilers Forum.
• Animations, artwork, icons and other such material can be posted within these threads but they must not be used across Fan Forum or any other thread.
• Discussion and information sharing must be limited to the listed threads that have spoilers indicated in the title.
• If you're unsure about what might be considered to be a spoiler please continue to use the spoiler tags, shown here: [sp][ /sp]

Pictures

• Pictures from promos that have aired on television, been shown at the movie theatre, or are from general promotional material at official websites and/or aired on places like YouTube or published in magazines are not considered to be spoilers.
• Pictures of clips, episode stills and filming pictures of scenes from an upcoming episode or movie that are available on the Internet and have not been aired on television or have not been shown at the movie theatre before the movie is released are considered to be spoilerish, and they should only be posted in designated threads for the upcoming episode or movie.

Avatars

• Avatars made from promos that have already aired on television, been shown at the movie theatre, or are from general promotional material at official websites and/or aired on places like YouTube or published in magazines are not considered to be spoilers.
• Avatars made from sources other than the ones mentioned above should not be used until after the episode airs or until the movie is released, because avatars can be seen all over Fan Forum, and we want to respect the wishes of members that don’t want to see any spoilers for an upcoming episode or movie.
