The panel on the left displays image information such as:
• Filename path
• Image size in pixels
• Alpha channel status (whether or not the image contains alpha channel

The left panel also has tools for creating or modifying the alpha channel
and softening the edges of the alpha channel (also softens the inserted key
effect).
