[Theme: EvoLve] blog page full width stretching images how to make smaller?

Hi there, I am using the Evolve Theme and besides loving it am trying to figure out how to fix the blog page. Currently, because I want to have it ‘full-size’ so I don’t have the sidebars appear on this page it is stretching the images to huge proportions, I want it to have either one or preferably two columns of blog posts that look more normal and compact. Here is the link to what I am seeing: http://www.legallyunconventional.com/blog/

If I change the ‘full-size’ off, it will mess up my formatting on other pages. Please help! Thank you!
