mobile version layout – images in the wrong place

Hello,
could you help me please? My site looks fine on desktop but the images are stacking in the wrong place on mobile.

I would like the layout to be text then image, text then image. At the moment it seems to be text, image, image, text.

I have included a screenshot link so you can see what I mean.

many thanks in advance
Kim
