So excited to see this on the release notes.
When providing it in my themes a bit disappointed, so have delayed it. You need to distinguish in the function call what to relate (images,albums,news,pages), with no thumbs for images.
Why can't you just relate ALL being it is on tags only. So you can have this function call on a sidebar, say, and it does not matter if you want albums, images, news, pages, etc, if their are objects with the same tags they are listed.
Then depending on the objects listed, they may have a thumbnail. Sorry, but when you list related images, you have to have a thumbnail (display of an image).
Nice addition, wish I would have examined it earlier...
Edit: Oh also - can you put a html wrapper with a class on it please!!!
