Scale images

I would like wide images on pages to scale for smaller screens and handheld devices in a manner similar to the way the main slider scales.
Currently images larger than 215px wide simply squish and distort on smaller screens.

Theme: Colorway Pro Responsive Theme 3.2.5
Current page with issue:
http://www.earthartist.ca/natural_playgrounds/schoolyard-playgrounds/havergal-college/

 

Solved the problem - I needed to remove the size specification in the code automatically generated by the application.

Thanks anyhooo
