I have setup rtmedia along with buddypress. Enabled masonry grid but it shows all the images one below one.
Below is the setup
Use lightbox to display media–>ON
Number of media per page-10
Enable Masonry Cascading grid layout –>ON
Enable Masonry Cascading grid layout for activity –>ON
Number of media items to show in activity stream-10
Sizes–>for some reason the size mentioned in medium are used in activity grid. If i change in medium, these are impacted in activity images.
