Below are some things we've dropped support for, due to low usage, and how to manually implement them.
Image classes
Add these to your "Additional CSS":
.feast-image-double-frame, .feast-image-double-border { border: 5px double #777; }
.feast-image-pivot { -ms-transform: rotate(4deg); -webkit-transform: rotate(4deg); transform: rotate(4deg); }
.feast-image-casablanca { -webkit-filter: grayscale(100%) contrast(110%); filter: grayscale(100%) contrast(110%); }
