- optimization : representative picture becomes mandatory for a non empty
category. So, at each insertion in images table for a category, a new representative element is elected (by rand). This must be improved by not reelcting a random picture admin set an element as representative manually. - optimization : recent cats page only needs 2 queries instead of 3*N (N categories to display). The bad point is that it shows representative element of recent cat and not a random element among recently added. - optimization : empty cats page only needs 1 query per non empty sub category instead of... a lot. For each sub category, PhpWebGallery shows the representative element of a category chosen randomly in sub cats. Thus, get_non_empty_subcat_ids and get_first_non_empty_cat_id becomes obsolete. - new function get_cat_display_name_cache to show category names with a caching for all gallery categories names. This function, to the contrary of get_cat_display_name shows names in the correct order... git-svn-id: http://piwigo.org/svn/trunk@610 68402e56-0260-453c-a942-63ccdbb3a9ee
