This is my wordpress site. it is part of a multisite network
West Side Stories/
I regularly create featured posts on my wordpress site, and every featured post has a featured image. These images are supposed to be 650 pixels wide and 250 pixels tall. Underneath the featured image are displayed thumbnails of the last six featured images. These featured images are created out of the 650x250 image, rather than existing as separate images. Ideally, I would like to keep things that way. The problem I have is that the thumbnails are supposed to be square, but are sometimes just rectangles. At the date of posting, three of the six thumbnails have this problem.
These two pages seem to bear passing resemblance to my problem, but I can't find any answers on them:
Thank you in advance for the help.
