Problem with behavior of image moving over text when scaling the page

Hi there,

I am having some problems with the images on my website. When I am scaling the website, the image goes over te text. See images down below.
My aim was to let de images scale the same way like the columns at the bottom of the page. I thought I had achieved this, but now this is the next problem to tackle.

Hopefully someone can help me out, thanks!
