Zenpage-default theme's gallery.php uses just the normal album thumb function that is set by the admin options:
Line 35: `<?php printAlbumThumbImage(getBareAlbumTitle()); ?>`
Actually I meant to use the same there as on album.php which I admit to have forgotten. This is on album.php:
Line 34: `<?php printCustomAlbumThumbImage(getBareAlbumTitle(), NULL, 95, 95, 95, 95); ?>`
If you don't have you should review the theming tutorial and look at the functions guide.

Yes, details on that are on top of `zp-core/i.php`
