Place this js in a theme (or embed media widget). In the js below the class .people-lop-lrg-pic is the class applied to the LOP widget.
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
<script>
jQuery(document).ready(function() {
// makes lop news pic use full size image
setInterval(function(){
jQuery(".view-os-news figure, .full-news-pic figure").each(function() {
jQuery(this).html(jQuery(this).html().replace("/styles/os_square_100_100/public", ""));
});
}, 250);
//PULL IN LARGE PROFILE PIC
//setInterval(function(){
jQuery("article.node-person .field-name-field-person-photo").each(function() {
jQuery(this).html(jQuery(this).html().replace("profile_thumbnail", "profile_full"));
});
//}, 250);
});
</script>
This is the end result. Note: additional css must be added for the circle images.
