Images not loading on 1st time view

Hi,
I can’t figure why, when someone loads my site for the 1st time, images won’t load.

Screens from different browsers:
mozilla: http://screencloud.net/v/8uDB
chrome: http://screencloud.net/v/xWSD
opera: http://screencloud.net/v/nR7d
ie (f#ck3d header) http://screencloud.net/v/n5FT
ie (f#ck3d sidebar) http://screencloud.net/v/L1U

Screens from page speed test websites (notice the tested url screenshot)
pingdom: http://screencloud.net/v/642V
gtmetrix:http://screencloud.net/v/4H4E
webpagetest: http://screencloud.net/v/i1ER (notice how repeated view is different from 1st view)

My website is currently running on a vps:

php info: http://technicamart.com/phpinfo.php
(for other system details just ask)

Installed and active plugins:
Amazon Simple Affiliate (ASA 2) – 99% sure it doesn’t conflict, tested without it being activated and same thing happens – no images on 1st view
Better WordPress reCAPTCHA
Contact Form 7
Google Analyticator
Regenerate Thumbnails
WP Smush
WPBakery Visual Composer
Yoast SEO
Jetpack by WordPress.com (running only protect and photon) – I’ve tried disabling and enabling photon countless times to see if it’s because of it, it is not.

My head hurts. What I expected to be an easy extract and install press of a button turned out to be hours of testing to see what the hell is wrong.
Already did some search on your forums before making this post. If you’ll recommend me to turn off image loading animation effect(lazy loading) won’t cut it for me as it was the major point that sold me your theme. Running your theme only with your recommended wp plugins also won’t cut it.

For the moment I’ve stopped using your theme. Will try it on a clean wp install in the next few day (even if does work won’t solve my current problem).

Till then, I need your help.

I’ve just sent you an email with admin credentials.
