Hi all,
I was reading many threads on forum and bugtracker that with usage of "tags_extras" plugin one can fetch tags from images to album and sub-album and print.
I am no programmer so If one can guide.
How to put it simple ways to show it on renderings of output.
As with other plugins you need to place the function(s) it provides on those the theme pages where you want to use it and on these in the place where you want to use it. You don't need to be a programmer.
The functions follow the way the standard function printAllTagsAs(). All functions documented here:
http://www.zenphoto.org/documentation/plugins/_zp-extensions---tag_extras.php.html
If the page stops rendering mid-way it is an indication of a fatal PHP error. So you need to find that error in your server logs or the Zenphoto debug log.
There are any number of reasons why this code might fail. For instance if it is placed where the variable $_zp_current_album might not be defined you will get an error. So without knowing the error we really cannot help correct it.
