you need to make a custom trophy case with a widget like "custom post" for unofficial trophies, there you then can copy the link of the image into that widget to display your trophies. Official pmc trophies get automatically added if you have the widget active, just click on widget on your profile page and scroll through the available ones til you get "trophy case" for the pmc held contests trophy display case. And for the custom trophy case, go to custom post and activate one of the three there, place that somewhere on your profile (like next to the PMC trophy case) and enter in the images (of the trophies) with the option edit widget then selecting the insert/edit media option, there copy paste your won trophies in community member held contests and they'll be on display.
