i really will appreciate your help about a problem that i have with sorting.js

the code is:

2. /* SORTING */
3. if (jQuery('.show_album_content').size() > 0) {
4. var $container = jQuery('.portfolio_grid_isotope');
5. } else if (jQuery('.portfolio_packery').size() > 0) {
6. var $container = jQuery('.portfolio_packery');
7. }
8. 
   
9. jQuery(function () {
10. if (jQuery('.show_album_content').size() > 0) {
11. $container.isotope({
12. itemSelector: '.element'
13. });
14. } else if (jQuery('.portfolio_packery').size() > 0) {
15. $container.isotope({
16. itemSelector: '.packery_item',
17. percentPosition: true,
18. masonry: {
19. columnWidth: 1
20. }
21. });
22. }
23. 
    
24. if (jQuery('.show_album_content').size() > 0 || jQuery('.portfolio_packery').size() > 0) {
25. var $optionSets = jQuery('.optionset'),
26. $optionLinks = $optionSets.find('a'),
27. $showAll = jQuery('.show_all');
29. $optionLinks.on('click', function () {
30. var $this = jQuery(this);
31. // don't proceed if already selected
32. if ($this.parent('li').hasClass('selected')) {
33. return false;
34. }
35. var $optionSet = $this.parents('.optionset');
36. $optionSet.find('.selected').removeClass('selected');
37. $this.parent('li').addClass('selected');
38. if ($this.attr('data-option-value') == "*") {
39. $container.removeClass('now_filtering');
40. } else {
41. $container.addClass('now_filtering');
42. }
44. // make option object dynamically, i.e. { filter: '.my-filter-class' }
45. var options = {},
46. key = $optionSet.attr('data-option-key'),
47. value = $this.attr('data-option-value');
48. // parse 'false' as false boolean
49. value = value === 'false' ? false : value;
50. options[key] = value;
51. if (key === 'layoutMode' && typeof changeLayoutMode === 'function') {
52. // changes in layout modes need extra logic
53. changeLayoutMode($this, options)
54. } else {
55. // otherwise, apply new options
56. $container.isotope(options);
57. }
58. return false;
59. });
60. }
61. });
62. 
    
63. jQuery(window).load(function () {
64.     if (jQuery('.show_album_content').size() > 0) {
65.         jQuery('.portfolio_grid_isotope').isotope('reLayout');
66.     } else if (jQuery('.portfolio_packery').size() > 0) {
67. $container.isotope('reLayout');
68. setTimeout("$container.isotope('reLayout')", 500);
69. setTimeout("$container.isotope('reLayout')", 1000);
70. }
71. });
72. jQuery(window).resize(function () {
73. if (jQuery('.show_album_content').size() > 0) {
74. jQuery('.portfolio_grid_isotope').isotope('reLayout');
75.     } else if (jQuery('.portfolio_packery').size() > 0) {
76. $container.isotope('reLayout');
77. setTimeout("$container.isotope('reLayout')", 1000);
78. }
79. });
 

when i click on the page of gallery with this sorting script i have this result:

as you can see doesn't load well the images, just a row. The pics are correctly loaded If a refresh the page.
Someone could help me?
