The Media Library design (database module) has been adopted for Photo Station 3.x and later versions. The folders containing your photos and videos need to be added to the media folder list. Please set up the media folders in
“Control Panel” > “Applications” > “Media Library” > “Media Folder”.
If you still do not see your photos and videos showing up in the Photo Station, please make sure you have appropriate access permissions (at least read permission.) Folder and file permissions can be set in “Control Panel” > “Privilege Settings” > “Shared Folders” > Access Permissions”.
