Wherever you need to display a media, a "Select Media" window will show.

Under the "Upload Your File" tag, you can select media from your computer and all those uploaded media go to the "Library" tag. So that from now on you can pick the media in the library instead of uploading it again.

UChat just add a new feature to allow you to delete media in the library. Simply hover over the media and a red delete button will show, click on the button to remove this media from the library.
