 * Hi, I want my featured image thumbnail that shows on the homepage for each post
   to be square. I uploaded a square image but it crops the top and bottom into 
   a rectangle. Can I change it to a square? If not, can I get the measurements 
   of the set size for those thumbnail spaces so I can create an image accordingly?
 * Thanks,
    Naomi

 * Hello Naomi,
 * The post featured images are cropped down to 340×220.
    This custom size is defined
   in functions.php.

 * Am I able to change it in functions.php or will it go crazy and ruin everything?
   I’m very inexperienced with code so very cautious.

 * You should be able to easily change it, just search for the values that I provided
   above.
    Once you change a custom size, you will have to install, activate and
   run a plugin like Regenerate Thumbnails.
