Hi Hector! Thank you so much for your wonderful plugin. My sidebar wouldn't be complete it. I am in the process of widening my sidebar by 65 pixels and I'd like to enlarge the size of my popular post images to fit the new 300 pixel width. The problem is that when I try to enlarge the size of the popular post images from 108 pixels wide to 140 pixels wide, the pictures are no longer squares.
Here's how my popular posts look at a width of 108 pixels:
And here's how they look after I change the settings to 140 pixels:
I am very hopeful that there is a way to fix this, and if you could give me guidance on how to do so, I would greatly appreciate it! You can see my sidebar at cookieandkate.com.
