I uploaded images to be used in the slideshow and sized at 940x423, 940x417 and a couple of others. The images USED to work, and now they all are appearing too large for the slideshow and not auto-cropping correctly. I've tried changing the size of the images in the Media folder to be smaller than the required size, cleared my cache and refreshed the browser, but the images STILL do not change size and they are too large for the slideshow.
This is not the first time I've had this challenge - why does this happen? It's getting frustrating - I never know when the sizes will change on me. How do I permanently fix the slideshow so the images aren't too big?
