Thank you for your fast response, Yigit!
All product images are actually 500 x 650 but they adjust themselves to 450 x 450 so they still do not display properly. I want to be able to override these settings that make the photos 450 x 450 and be able to adjust the height of the columns so that they can display my products properly. Would you be able to provide me with the source file where I can adjust the height for these columns? How can I make sure that all of my products display as their original size and do not get adjusted down to 450 x 450?
Thank you!
