Remove background corner from images

I was able to make the image round use custom CSS but I can't remove this pointy shade on the corners. Any idea on how to remove it?  Thank you!

It is image overlay. You can turn it off in Site Styles, or add this to Design > Custom CSS

/* Disable image overlay */
.image-overlay {
    display: none !important;
}
