Thumbnail Size

I am using a theme called Huex. I have resized the thumbnail images but it insists on using a set size. I believe this size is in a js file? I am really not sure but I really know little about js and php. Is there any way someone could look at it for me and tell me what they think?

If you go to http://www.droidedup.com/testing/droidedup and inspect the small thumbnails in the featured section, you will notice a <li style="width: 34px; display: list-item; " class="">. The thing is in my css I changed that width to 50 x 50 but it insists on using 34px for the image width. Does anyone have any idea where I can find out why this is happening? According to my developer tools if I inspect the element there is a “Style Attribute” that is set already.
