Hi, we have problems with the header image of homepage slider, it never fits with the page width. We have edited it at 1018/460 but it is always narrower than the page. We can not make a panoramic view, the images tends to get square. We tried with wordpress and lightroom photo editor several times.
I hope you are well today and thanks for posting here.
Could you please share me your site URL where it’s happening so that i can troubleshoot it?
Yes the slider images should be at least of the size 1018px X 460px but the images used in the slider on your shared site is smaller than it as shown here http://i2.wp.com/esencianimal.com/wp-content/uploads/2015/12/DSC_0758-e1455995720958.jpg?w=690
So please make sure to use large images and then use the following plugin to regenerate images sizes.
