Hi,
The missing image issue is due to a deprecated class file name. I tried to change the template files on the server via the back-end, but it does not let me.
To fix that, you will have to edit the wp-contentthemes/{your-theme}/asp/isotopic.php template file, line 50, this section:
class='asp_item_img'
to..
class='asp_img'
..that will resolve that.
The trigger is not working because the mimimun number of characters the user needs to input is set to 3. If you change that to 0, it will resolve the issue: https://i.imgur.com/eD0AY1X.png
