Hi,
this is possible, you can change size of stored image from Avatar field configuration, of course to show a page like screenshot you need also to add few lines of CSS.
for example with a CSS code like this you can see a page like screenshot from this site (keep in mind that we use square small images, but you can set resolution and ratio from avatar options, also you can set number of column)
.jsn-l-avatar {float:none;margin:0;}
.jsn-l-avatar a,.jsn-l-avatar img{width:95%;}
.jsn-l-title,.jsn-l-fields{display:none;}
You can test this also in Free version.
