Just use
[album=1]
[album=2]
[album=3]
[album=4]
etc.. on the same page and customize the output for each album? Something like;
<div class="album">
<h3><a href="#" rel="showmore">Album title</a></h3>
<div class="more">
<div class="gallery1">GALLERY 1 CONTENTS</div>
<div class="gallery2">GALLERY 2 CONTENTS</div>
<div class="gallery3">GALLERY 3 CONTENTS</div>
</div>
</div>
<div class="album2">
<h3><a href="#" rel="showmore">Album title 2</a></h3>
<div class="more">
<div class="gallery1">GALLERY 1 CONTENTS</div>
<div class="gallery2">GALLERY 2 CONTENTS</div>
<div class="gallery3">GALLERY 3 CONTENTS</div>
</div>
</div>
Then slap on a script to “showmore” so that when one click for let’s say “Netherlands” a script slides down the galleries for “Netherlands”. You can use mootools + fxSlide or some jQuery script for that, it’s kinda straight forward.
OR if you want it even simplier you can just create sub-pages for a page and use WP’s built-in system for displaying sub-pages on the “main page”, the sub-pages of course being things like “Netherlands”, “Germany” etc. On each sub-page you simply just include the corresponding Album.
/your-gallery-page/netherlands/ = netherlands album + it’s galleries etc.
Each album will then simply be a sub-page and child of “your-gallery-page”.
Edit: The mootools / jquery -solution is a bit cooler and faster for users to browse your albums, however be warned that it actually will load every gallery-thumbnail so it may tax your gallery-page a bit if you have a thumb-per-gallery and if those thumbs weigh too much (setting it at 60% quality instead of 90% is a good idea for example).
Hope you find my quite messy post usable in some way. ??
