My sliders all worked fine. Images were pre sized before loading and set at 670x 400. I was editing another page with no slider and scaled down an image using wp library image editing. When I went back to the home page I found all images in all sliders cropped to about 150 x 400? px. Some not even that just a slit of an image. Does anybody know what's happened and how to fix it? Are the two events related?
