We are using Symmetry by Clean Canvas, and I am struggling with some of my images not displaying correctly. Specific images seem magnified and cut off even though they display correctly on the products page. I have been reading about aspect ratio, dimensions, etc., and it doesn’t help. I have tried to adjust the width and height to no avail. I hope someone in this community knows how to adjust all photos to fit correctly. The First photo is from the slideshow on the home page, and the second is the same photo in products page??? I appreciate your support on this matter 
I am having the same issues. Any image I import is either too small or too large with seemingly no way to change it. The image sizing in shopify is just really screwed up. I wish in the web based editor we could just grab a corner and resize it right there, but that would make too much sense. Hopefully we can find a solution to this.
