What its doing is.
i upload my feature image which is 117×228 which should be big enough that it doesnt stretch it,but on the achievement list its trying to take a thumbnail or 51×100 and use it for the image on the achievement list,so it stretches it out.
i see that you can re-size them through css with this
.badgeos-achievements-list-item .badgeos-item-image img {
width: 50%;
height: auto;
}
but set to 50% it blurs the image
