To upload to your Media, click on the “+Upload” button at the top right of the "My Media" page. This will open the uploader modal window, which displays the compatible file formats that can be uploaded.
You can upload media two different ways:
1. Click on the “Add Files” button to open the file browser and select the files you wish to upload.
2. Drag files from your desktop or file browser onto the gray panel of the uploader.
Only files with the following extensions can be uploaded: JPG, GIF, PNG, SWF, MP4, and FLV.
NOTE: Playback performance can be negatively impacted by very large files. For optimal on-screen quality, files should be no larger than 20 MB.
