problem with images after refresh website (1 reply)

Hi

i run directadmin+nginx1.8+php5.4 php-fpm

when i do refresh to website the images not refresh good, sometime after refresh it put images in wrong place or double the images
you can look on this website rhost(dot)biz, you can try refresh few times and look on the images and you will see the problem.
