Using atahualpa 3.4.1 with category pages as excerpts and NextGen Gallery plugin.

Assuming that there is a category wich posts consist only of NGGal galleries, and a category page, how can I make these gals appear in excerpts?

Now all I have is just a list of posts titles.

you might want to post this on the nextgen forum since it is not a theme issue (ie, the same question would probably apply to all themes).
