Courses not responsive

Good afternoon guru's, I have a challenge with CoursePress that I'd like to throw your way. I have built a learning site where I am using a different theme than the coursepress theme and the theme is responsive when it comes to different screen sizes (mobile and tablet) for every page except for the courses page (ie, the page where all the courses are shown). I have attached a screen shot of the course layout on my iPhone 6. It seems to be the course images, so is it possible to turn the images off for mobile devices, or do you have any other ideas on how we can solve this issue? Thanks Steve
