I Find that coppermine shows a pictures in different album according to album keyword & uploaded picture's keyword.
However i don't want to show pictures of one album of one category to album of another category.But want to show it in different albums of same category.
Is it possible?
The easiest solution (without code changes) will be to use different keywords. I currently don't know how much effort it is to add such a functionality you ask for. What exactly do you mean with "the same category". Depending on how your gallery is structured it maybe has sub-categories. E.g.:
Quote- cat 1
-- album 1
-- album 2
-- subcat 1
--- album 3
- cat 2
-- album 4
Should pictures of album 1 also be display in album 3? They don't reside in the same category, but belong to the same top level category. Adding a check for the same, and just the same category (i.e. in my example just album 1 and album 2) is probably a quite simple code change.
