Unfortunately it’s not possible to directly view your Library.
It’s only available when you are in the process of creating/replying to a Post or Topic or a Message and you click on the ‘Choose a File’ link.
You can always create a new Topic, use that to access your Library and then remove the Topic when you have finished.
We’re looking at ways to make direct access possible, but haven’t found one yet.
Please note … if you Delete (red button) an image in your Image Library then it will also be deleted wherever you have used it in Topics and Posts in the Forum.
