This is how Wordpress plays “Joy Whack a Mole”:

Me: Yay, I made a neat new logo.  Happyhappyjoyjoy.  (Tries to install it on Wordpress.)

Sempress Theme:  I insist that your logo be 50px X 50px.

Me: Are you daft?  Do you know how tiny 50 X 50 is?  That’s almost as small as a favicon. it looks silly.

Sempress Theme: Muhahaha!
