Pictures Per Page
When viewing an album, this controls how many pictures are displayed before pagination occurs.
When enabled, all new pictures are placed into moderation. This can also be enabled in usergroup permissions.
Album Thumbnail Size
The maximum height and width of thumbnails in the album system. Each picture's aspect ratio will be maintained when it is thumbnailed.
Caption Preview Length
The amount of characters from a picture's caption that will be shown when a user hovers over the picture.
Number of Pictures that can be Uploaded Simultaneously
This controls the number of pictures users can upload simultaneously. They will not be able to violate any album- or usergroup-implied size limits if you set this value too large.
Maximum Pictures per Album
You may choose to limit the number of pictures that a user can have in one album. This is primarily useful for encouraging your users to have albums for smaller topics, but it does have minor performance considerations as well. Setting this to 0 disables the limit.
Enable Picture Comments
Set this option to yes if you would like to enable commenting on album and group pictures. Comments are associated with the picture itself, so comments will be shown anywhere the picture is shown.
Moderate Picture Comments
When enabled, all new picture comments are placed into moderation. This can also be enabled in usergroup permissions.
Default Picture Comments Per-Page
This setting allows you to define the default number of picture comments displayed per-page with a picture.
Maximum Picture Comments Per-Page
This setting allows you to limit the number of picture comments users may display per page with a picture.
Allowed BB Code Tags in Picture Comments
This setting allows you to enable and disable the use of various BB codes in picture comments.
