Hi Sara,
I reviewed your website and I’m assuming that the stock photos that you replaced were located on the sites homepage. If that’s the case it seems the images are scaling properly now. The three images located under your page hero as well as the images under “Current Residents”, are the only ones I see that you might be having trouble with.
Lots of times when you make edits to your website the changes will take effect on the back-end, but still be cached into the site or web browsers database causing the elements not display correctly. In this case you need to clear all caches associated with the site.
I Hope this helps! If you are having trouble getting images to respond on a different page please reach back out to us with that pages URL so that we can review it and help you troubleshoot.
