jQuery $.post return incomplete data

Question

I've come across a strange behavior of a $.post command. I have an AJAX request by $.post(param,returned data), which loads pictures onto the page of the visitor.

This is the code, with a little bit of animation:

function showPicturesByCat(cat){
$('.local-overlay').fadeIn(200);
$('#picturesByCat').stop().animate({height: '0px' },200);
setTimeout(function(){
    $.post('./ajax/populate.php',{operation:'show-pictures-on-front',cat:cat})
        .done(function(data){
            $('#picturesByCat').html(data);
            setTimeout(function(){
                var inaltime = $('#picturesByCat')[0].scrollHeight+20;
                $('#picturesByCat').stop().animate({height: inaltime+'px' },500);
                $('#picturesByCat').css({opacity: 1});
                $('.local-overlay').delay(500).fadeOut(300);
            },300);
            $('html, body').delay(200).stop().animate({
                scrollTop: $('#picturesByCat').offset().top
            },300);
        });
},200);
}

On the PHP side, it's just a loading of pictures with names inside a database, based on the chosen category (cat). Code works perfectly ... on PC,s, but when it turns to mobile, both Chrome and Firefox do the same wierd thing. When I choose a category, the pictures loads but not completely. If you scroll to the bottom, you'll see the thing. If I tap the second time on the same category, the pictures loads completely.

Here's the address

I can't figure this out, it's too wierd for me. Maybe some of you can spot or already know what it's wrong.

Edited:

this is the dump data, as requested in comments.

Hope it helps, although I can't see anything wrong.
