This is a very simple community setup strictly for the announcement of separate journals dedicated only to a person's photography. In other words, if your personal journal has lots of pictures, that doesn't make it a photo journal as far as this community is concerned.
No images please, that isn't what the community was setup for.
Please use the <lj user="my_photo_journal"> custom tag too. Thanks.
Although not required, it would be nice if people made the announcement from the account that is their personal journal.
Now that the LiveJournal invite code system is gone, I hope that all photographers on LiveJournal will consider setting up a separate journal to showcase their works. :-)
