If you mean this
We can adjust our featured images in our blog by going to Customize > Blog > Featured Images.
It didn’t work on my site
http://admirable-dogs.com/
– so I resized the images in my graphic program and hard linked the images
Where I didn’t do it, and used the Featured image option it created many more problems I am trying to resolve
But I will also try GP on my other site, it may by the host setup. I’ve already had problems with this one.
Thanks again
