How to standardize the images in the radio widget?

I know I pulled these images from the internet so it can be displayed as radio buttons but is there a way to standardize all the images to one size although I pulled them from the internet in different sizes?

Or is there a way for the image to not appear on the emails and just the text that appears below. 

Unfortunately, for the image radio buttons, the size of the image when sent to the email could not be modified. So, your best solution is to create your own resized version of your images and use it for your radio button images instead.
