Hello,

I need a gallery manager for my TGP site, is possible to add custom banners to each gallery and sub galleries?

For example, I will make a group of sub galleries on the galley "Section 1" I need a custom banner for all these sub galleries.

Banners for section 1
Section 1 > Gallery 1
Section 1 > Gallery 2

Banners for section 2
Section 2 > Gallery 1
Section 2 > Gallery 2

Thank in advence

Please use the right terms. Please see the glossary. You are talking about albums and subalbums...

Several possibilites:
1. Edit your album.php page with a check for hte current album etc.
2. Use the multiple_layouts plugin and create album layout pages to assign to certain albums.

In any case you should have read (and understand) the theming tutorial before starting on this.

Short answer, "yes".

Zenphoto is completely customizable, including you can make yoru own theme which does whatever you wish.

There are a number of approaches depending on what you want to accomplish. Simplest is probably to place code in the album.php script that detects the conditions and displays the appropriate banner.
