Argh.I meant style.css not slider.php
This worked for me as well. I had to resize some of my photos but that was all. I went with 300 pixels.
I placed this code in the slider.php file found under the editor tab in the left hand column (click on Appearance). Just do a search (Ctrl+F) for “.slides” and place it after the first instance. You may need to remove the comma but not sure.
