images are too large on only one specific page

i would like to understand as to why only in one specific page of my site that is the page called people eyewear by michel atlan why is it that wehn i click on any photos of that page the photos come up to the screen really large it use to be in a fair size a few days ago and now it is too big to view it
it take almost the all screen to view one image
does that come from some kind of setting that needs to be made so it goes the photos goes back and show up to a normal size thank you
