 * I am working off of the thumbnails template to create my own template. I need
   to change the thumbnail sizes. I found information on how to do it [here](https://wordpress.org/support/topic/thumbnails-size-5?replies=4)
   but it is not working for me. I have a folder in my theme folder called cycloneslider.
   My template is inside that. I have edited the slider.php to show the thumbnail
   size that I want to use. I also copied the cyclone-slider.php file and changed
   the thumbnail size on there. I always come up with an error “Notice: Undefined
   index: 580 200 crop.” That is the size I want for my thumbnails. And, obviously
   the thumbnails do not show up. As far as I can tell everything is defined and
   it seems to not be loading my edited cyclone-slider.php file. Any feedback would
   be very helpful. Thank you.
