page loads incorrectly

Hi there,

I have the following issue:

My page loads incorrectly (gallery photos are compressed), however, when I resize the browser window everything on the page immediately shifts to its correct position. The error happens on Chrome and Firefox and doesn’t seem to be correlated with any other plugin running on the site.

I have screen recorded the issue and uploaded it to YouTube so you can see what I mean.
