Pictures not staying the same size

Pictures not staying the same size

I have three pictures on my home page.  There is a highlight box with the picture in the image at the top as a menu header, and a paragraph at the bottom.  If I make any changes to the page that cause a refresh or if I initiate a refresh myself,f the pictures change size and part of them is cut off.  They are set to "fit".  In order to fix them I have to switch them to "small" and then back to "fit".  This means however that if I forget to do this when I publish changes, the published page will look not look right.


Anyone else have issues like this and if so do you know a fix?
