Thank you for your reply however I may not have been clear in my question. The problem seems to be that the Slider zooms into a portion of the image and then crops it. For example in my case I have a horse with a rider. This image is 1170 x 650 or even greater. When the image is rendered in the slider it will show with the head cutoff the rider and the legs cut off the horse. It seems to select a centroid, then zoom in and then crop at a designated size outside of this new zoomed area. In some cases it doesn’t matter and the new image is acceptable but in others it looks wrong even though the original is complete. The image was originally very high res and I simply scaled it down whilst maintaining the aspect ratio. So the new scaled image looks exactly the same as the original but just at a lower scale.
Thanks
