This may get you started:
In index.php change
`
<?php printAlbumThumbImage(getBareAlbumTitle(),'check-flagthumb'); ?>
`
to
`
<?php printCustomAlbumThumbImage(getBareAlbumTitle(), 400, NULL, NULL, 400, 400, NULL, NULL, 'check-flagthumb'); ?>
`
In `/js/libratus_zp.js` change
`
$('.gallery-thumbs-large').justifiedGallery({
rowHeight : 180,
maxRowHeight : 200,
lastRow : 'nojustify',
cssAnimation : true,
margins : 20
});
`
to
`
$('.gallery-thumbs-large').justifiedGallery({
rowHeight : 400,
maxRowHeight : 400,
lastRow : 'nojustify',
cssAnimation : true,
margins : 20
});
`
And in the theme option `Custom CSS` enter:
`
.jg-entry.entry-visible {
max-width: 400px;
}
`
Btw, the website in your user profile appears to be hacked.
Better remove or change that.
